I have installed the marvin beans package and its supposed to hold the marvin ole, or not? but there isnt any marvin ole on my computer and on the save as... option i cant choose it nether...ive red the topics but im not intelligenter as before....


If the installation stops and an error popup is displayed, check the running processes in Windows Task Manager: if marvinOLEServer.exe is running, please stop it manually. This may occur when an MS-Office document is just using Marvin.


Never before have I used a chemistry sketching program, no maybe a program in general with UI so damn good, it feels so natural to use. I was drawing some coordination complexes and the ctrl-c function allowed me to make a ghost of whatever Ligand I wanted and a single left click would replace any atom with that ligand. It reminds me of copy pasting objects in garry's mod where you get a ghost of the object and get to position it. Between that and seamlessly changing bond type. The fact that it is chemically aware of mistakes (which is actually one of it's downsides, it is harder to draw less common compounds with unstable features) makes it great for sketching out simple compounds easier.






Marvin Sketch is the fast and accurate software used for drawing of chemical compounds and reactions. This software also provide guidance and is integrated with calculators for obtaining the suitable results of properties. Marvin sketch 20.8 software is well equipped with advanced chemical viewer for studying the chemical structures both single and multiple 2D/3D, as well as chemical reactions and its related data. It can display all the details, like molecule name, generated IUPAC name and SMILES strings of molecules. With the help of Marvin Sketch 20.8 software the compound N'-[(1E)-1-phenylethylidene]-1,3-benzothiazole-2-carbohydrazide(PEBTH) is characterized and all its properties were determined.


Taking into account of relative abundance of the isotopes the mass distribution of the input molecule PEBTH is calculated using Marvin sketch software. This distribution of mass is demonstrated as a spectrum and this spectrum in mass spectroscopy is known as the m/z:relative abundance spectrum.


Molecules in general contain specific functional groups that can lose or gain protons under suitable conditions. The coincidence of the protonated and deprotonated forms of the molecule is described by a constant value of pKa. In marvin software by making use of the pKa Plugin it is possible to calculate the pKa values of the molecule. It is well known that the based on its partial charge distribution the pKa value of molecule changes.


If you do not use Marvin Beans installer but you need both Marvin and OLE server, you have to do the followings:Download marvinbeans-VERSION.zip and JChem_NET_API-VERSION.msi.Unwrap the marvinbeans-VERSION.zip.Launch the downloaded JChem_NET_API installer in administrator mode.Run installole.bat in administrator mode with the following parameters from the lib folder of the Marvin Beans packageto register the location of Marvin Beans package for the OLE server.installole.bat /c "MARVINHOME\lib" MARVIN_VERSIONwhere MARVINHOME is the absolute path of target directory where Marvin has been installed to and MARVIN_VERSION is the version id of Marvin release.E.g.:installole.bat /c "C:\Program Files\ChemAxon\MarvinBeans\lib" 5.3.4If installation has been successful, you will find OLE Server resource in the

 C:\Program Files\ChemAxon\Shared\MarvinOLE folder.


Marvin OLE: This logging folder represents all logging information written out from the embedded OLE sketch. CXNEmfExporter: This logging folder contains log files by EMF picture generator, EMFExporter component is responsible for antialiased picture rendering. CXNdotNetClassCOMLoader: This logging folder contains log files if .NET components are about to be loaded, typical case when .NET version of Marvin OLE is running. CXNMarvinOLEWrapper: OLE Wrapper component is typically used in browser based ChemAxon solutions e.g. SharePoint data editing. CXNOLEClient: OLE Client component is used in thick client applciations for Marvin OLE conversions, e.g. JChem for Excel. Component specific folders can be found in the ChemAxon root folder under the following locations: Windows XP: C:\Documents and Settings\CURRENT USER\Application Data\ChemAxonWindows Vista or above: C:\Users\CURRENT USER\AppData\Roaming\ChemAxonIf the users turn to support help, these folders need to be zipped and sent to the relevant support team/department. Please take care of that log files might contain confidential local information (molecules) therefore log files are better to be sent directly to the support teams. Forum posts are public and searchable for other users therefore should be avoided for any log file uploading. Support teams handle the logging information confidentially.How to set loggingIn Marvin OLE (but also true for other components listed above) the verbose and style of the logging can be set in the following location of the registry:HKEY_CURRENT_USER\Software\ChemAxon\MarvinOLE.Under the Verbose registry key there are five options to be set: DateFormat: The default time format of the logging is %H:%M:%S. Log files are separated by dates so the relevant date information can be seen in the name of the log file as default. User can freely customize it to include full date time if necessary. Microsoft DateTime formatting guidelines  FileExtension: This setting contains the file extension of the log file. FileName: The name of the log file can also be changed, but it should keep the rules of file name generation under Windows. Level: This is the most important setting for both the users and the adminsitrators. It allows to change the verbose level, i.e. how much information the log file needs to contain. FATAL (0): Reports only fatal errors. We do not use this and it is not recommended. All error level problems should be logged.ERROR (1 Default): Recommended setting for error reporting.WARNING (2): Reports the more problematical things, which are not error but relevant for support.INFO (3): Lighter infromation, which can be very useful in the case of support.DEBUG (4): Development level information, e.g. Variable contents.ALL (5): All logging. MessageFormat: The default format is %s [%d]%s %s - %s e.g.: 23:59:21 [3]INFO MarvinOLE - C:\PROGRA1\ChemAxon\Shared\MARVIN1\MARVIN1.EXE Microsoft message formatting guidelines  %s : the formatted date/time stamp value indicating the moment when the log information arrives in the logger component. [%d] : level of the current logging %s : name of the current logging level %s - %s : application domain name - and the message itself   Event loggingAll CXN components, like Marvin OLE, also place error level log information in the System Event Log (in addition to the log file).Microsoft Event Log GuideEvent Viewer shows all types of logs, ChemAxon generally reports problems under the Application section. Troubleshooting and Administration Marvin OLE does not start or stopping with failure If the component cannot be launched by inserting into Office applications or the object cannot be copied onto the clipboard from Marvin Beans or from Marvin Editor component, then it hints an installation/uninstallation problem or a mismatch in the running mode. The first thing we recommend to check is the RunningMode flag in the registry. HKEY_LOCAL_MACHINE\SOFTWARE\ChemAxon\MarvinOLE This registry key is accessible only for administrators. HKEY_LOCAL_MACHINE\SOFTWARE\ChemAxon\MarvinOLE\Settings\RunningMode is decimal value numbering from 1.  RunningMode key is deleted! - Marvin OLE will be running in .NET mode by default. Java Mode (1) - Marvin OLE is running in Java mode. .NET mode (2) - Marvin OLE is running in .NET mode even if Java mode was installed. Data transfer mode (3) - Marvin OLE is running without GUI. (Not recommended)  If RunningMode is set to Java (1), Marvin OLE will search for the Java infrastructure, the Marvin Beans. To be able to find it, the following registry path should contain the referenced Marvin Beans isntallation folder and its version: KEY_LOCAL_MACHINE\SOFTWARE\ChemAxon\MarvinOLE\ReferenceFolders e.g. C:/Program Files/ChemAxon/MarvinBeans/lib 5.4.0.0 If it is not there, Marvin OLE cannot be launched in Java mode. In this case the administrator should either make correction in the referential folder by adding the correct path with '/' slash, or should delete the whole ReferenceFolders regsitry key, and delete(change) the RunningMode key to .NET (2).  This is the common problem, which might occur especially with early version of installers like 5.3.x series. If Sun Java environment damaged or no jvm installed locally providing jni bridge it is recommended for the adminsitrator to change the registry accordingly to .NET version or to repair the Java environment. Marvin OLE works without problem but does not display the molecule after editing In this case either the user should find a JNI invocation error in the Marvin OLE log, and check running mode (see above) or the EMF generator component has a problem and then its log file contains hints of the origin of the problem. The whole Marvin OLE needs to be reinstalled.  This case generally could happen when the user wants to install two different ChemAxon products with two different major versions. e.g. IJC 5.3.x and Marvin Beans or JChem for Excel 5.4.x. Marvin OLE editor is displayed not in the desired editing mode  For simple troubleshooting please run the StandaloneModeOff.reg/StandaloneModeOn.reg accordingly. If the desired mode is standalone editing mode (Marvin OLE is displayed in a separate window end it even runs in-placed) then it is worth running StandaloneModeOff.reg first and StandaloneModeOn.reg afterwards again to clear up the registry. Adminsitrator wants to set the Standalone Mode globally for all users but on some users machines it is still in in-palce editing mode. In this case it is worth checking if the user has overriden any global settings by a local one here: HKEY_CURRENT_USER\Software\ChemAxon\MarvinOLE\Settings\StandaloneMode. If this key contains 0 value, it means that the user has choosen the in-palce mode explicitly. The key either should be deleted or needs to be set to 1 for eliminating the problem.   Known IssuesWord Pad pops up a dialog indicating that Marvin OLE Server is not responding while inserting a new Marvin Document,or editing an exisiting one with MarvinSketch. This causes no harm or data loss, it is an invalid error message fired by Word Pad.After you complete the drawing process, and close MarvinSketch, press 'Retry' to close the dialog.
