Windows 2008r2 and 16bit soft

your problem has nothing to do with proxmoxVE
the 2008R2 server is the problem cause it exists only in a 64bit edition and 64bit systems can't run 16bit software, so you need to downgrade your server to 2008 32bit edition
 
Hello , i Have the same problem.... io had converted a phisical Server Win2008 standard 32Bit with Vmwareconverter.... and when i Run it with Vmware Player i don't have any problem... but when i run this vmdk in proxmox 4.1 the server run correctly but the program 16Bit don't work with this error... NTVDM.exe has stopped working.

what is the problem?

Many thanks for help
 
We had also such old windowssoftware. We sloved this by running these software with wine and dosemu/dosbox. This was always for us the easiest way. But yes it is depending on the complexity of your software.
