First read the little documentation vDos has to offer to make it run your application! Keep in mind you once had to configure DOS, the transition to Windows (XP?) took time. You forgot about that…

Have a look at the FAQs and Forum pages, eventually post your question/problem to the latter. The forum is monitored by Edward Mendelson and me, replies are mostly real quick.
If your issue however seems real specific to your situation/application, or you don’t want it public: Send an email to (change the "a" to an "o").

Submitting a problem or issue: Describe it as detailed as possible, eventually attach your autoexec and config.txt files. If your autoexec.txt starts another batch file, include that also. A mere “My DOS program won’t …” doesn’t help to come to a solution, how simple that even might be...
Trouble downloading: Check if you’re using a download accelerator and disable that.
