Insufficient DOS memory

Specs: Windows XP, 866 mhz Pent III, 512MB
I'm trying to install an old Win 3.1 program on my WinXP machine. The install goes OK until I get a message saying "There was not enough DOS memory available to perform the uncompression. Installation has failed." I've adjusted the .pif file to max out the extended and expanded memory, but that has not helped. I'd like to avoid a dual boot scenario. Any work around for this problem? Please advise.
Thanks, Jim

Try to install in Windows 95 compatibilty mode (option in the Link Properties); if that failed your only other choice to avoid dual boot is to download MS Virtual PC or open source VirtualBox (both are free) and run your program in a virtual machine. In that case however you need a legal copy of MS-DOS and Windows 3.1 to set up the guest anvironment (as to set up dual boot).

Chuck - Thanks for the quick response. The Setup.exe file is 32-bit and is published by Microsoft. I perused the links in your post, but didn't find anything that worked. Reading some of the other posts on this subject, it looks like I may have to set up a dual boot system. FYI, the app I'm trying to install is MathCAD 4.0 - the latest version of this program is prohibitively expensive. Thanks again.

Set config and autoexec. Some sp actually deleted them. Might have to use himem.


"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10
