Cannot uninstall PCNS 3.0 from SBS 2011 - error within...

[BillP]

I have a new SBS 2011 server which i inadventantly installed PCNS (x64) when I meant to install PC Business Edition.
During the install of PCNS it required Java (x64) which I downloaded from:

Java SE Runtime Environment 7
http://www.oracle.com/technetwork/java/javase/downloads/java-se-jre-7-download-432155.html

The install then proceded uneventfully.

I then realised my mistake and went to remove PCNS from "programs and features", when I tried to do so, a DOS window flashed very quickly (that I couldnt read) and the software didnt uninstall. I also tried clicking uninstall.exe from the program files directory, but that had the same effect.
After trying to uninstall many times, I eventually pieced together the error message....

"program is not recognised as an internal or external command operable program or batch file"

i believe this error will be easily reproducable as this is a clean system. Anyways, I then called APC tech support to obtain manual uninstall instructions. the support guy i got was a joke and couldnt help me whatsover - hence this forum post.

can someone assist with manual uninstall process? (and if anyone from APC is reading - the uninstall routine doesnt work)

Thanks

What you can do is delete the folder then reinstall pcnc then remove the program the correct wat to remove any registry clutter services ect

[BillP]

Please re run the PCNE setup and from there you should be able to remove that version of powerchute

Thanks, I have tried that - re-run the installer - it finishes with "Powerchute has been successfully upgraded"

I still cannot uninstall, same message.

If you can use system restore use it to restore your computer before you installed pcnc

Or Go To

My Computer>C:\>Program Files>And find a folder called powerchute and delete it or otherwise it will be called apc

not happy with just deleting the folder... this is a server and reliability is utmost importance. i cant be leaving behind registry entries, services etc
system restore is not an opion.

what i really need is manual uninstall steps

Ok, I have some info.

I have done some testing in a freshly built VM. It seems if you specify a volume to install other than C:, then the unstinall routine doesnt work **face palm**

So, I think the process will be as follows:

# Stop Java service
# Stop the pcns.exe * 32 service (BTW the 64bit agent runs as 32Bit !?!)
# Delete the following Reg key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\APC
# Delete the APC folder from Program Files
# Then reinstall PCNS using the defaults i.e install to C:
# Then uninstall PCNS

APC if you are reading, please fix this bug.
