PPR: Abnormal program termination: memory protection fault


Solution 1:

For maximum DOS Memory in an MS-DOS session, add the line:

LocalLoadHigh=1

to the [386Enh] section of the system.ini file.



Solution 2:

There are a couple of things to try in this situation. One solution that worked for me is as follow s:

Force Windows95 to allocate memory for command.com

In windows95, click on My Computer. Open Ms-dos_6. Find the command.com icon and _right_ click on it. When the pop-up menu appears, click on properties. Next click on the memory tab in the propert ies window. Set the Extended(XMS) memory setting to 1024. Also be sure that "uses HMA" is checked.
   All other selections should be set to "auto". Click on apply and OK. Then reboot Win95 and try r
unning ppr again.
