Problem with dvipdfm including eps: filtering file via command -->mgs.exe

I've been using dvipdfm since about 1996. However, when installing 
Windows 10, I've faced the problem translating the dvi with eps 
graphics. The utility reports like that: filtering file via command 
-->mgs.exe.....
I think I've recognized the place with problem: %o% in the command 
string for calling mgs.exe expanded into something like 
c:/users/myname/AppDataLocal/Temp//dvipdfm-x..... - there is double"/". 
  However, I couldn't find proper config option to eliminate one of "/". 
I suspect that this string is formed in .exe, and I think dpxfile.c is 
responding for that. However,  I'm afraid to change this rather 
complicated source code because it may lead to other error.

So, can anybody help me?
And, did anybody face the same problem?

Thanks in advance

PS My version of MiKTeX is from setup-2.9.5721-x64.exe
