PPR:  Abnormal program termination: memory protection fault


Solution 1:

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

Force Windows95 to allocate memory for command.com

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



Solution 2:

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

LocalLoadHigh=1

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