Hello. I run a programming development enviroment on Windows XP home in a non-admin mode. I've run this setup like this for a few years now. It installs in a non-administrative folder. Which is in its own folder on the root directory of the HD.

Code:
Microsoft (R) Program Maintenance Utility   Version 1.50
Copyright (c) Microsoft Corp 1988-94. All rights reserved.

        vc -DJAGUAR -O2 -c -o jag.o jag.c
Couldn't open <C:\DOCUME~1\CRUISI~1.asm> for output!
vbcc -quiet "jag.c" -o= "C:\DOCUME~1\CRUISI~1.asm" -DJAGUAR  -O=1023 -I/jaguar/i
nclude failed
NMAKE : fatal error U1077: 'C:\WINDOWS\system32\cmd.exe' : return code '0x1'
Stop.

C:\jaguar\hello>
I have installed, uninstalled and reinstalled the enviroment and rebooted several times to try and fix this. After a sorta recent fresh format C and reinstall of windows XP home it suddenly wants to not let me open these files in non-admin mode. The enviroment works great in the admin mode. No problems. But suddenly for reasons unbeknownst to me it won't allow access to it (as can be seen here) outside of an admin profile. Have never had this problem before with this setup on XP home.

I am stumped as to what to do. Tried everything I can think of. Tried Google etc.
