'Rolling back action' with AT&T Communication Manager installation

Question

PLEASE HELP!

I've been trying to help my friend install the communication manager on his PC for a week now with no luck. He's got a Compaq with Windows XP OS. I'm not a techie and he is also far from it but I agreed to help him get rid of some spyware that was installed. I manually deleted the rogue file and then installed SpyWare Doctor; the rogue was gone but so was the AT&T communicator.

I tried to reinstall the communicator software and the software goes through the set up process:

...goes through the initializing set up steps then...
'Updating component registration'
'Copying new files'
'Creating short cuts'
...goes through some other steps then...
'writing system registry values'
'registering product'
'rolling back action'
'The wizard was interrupted before AT&T Communication Manager could be completely installed.'

What I've done to troubleshoot; I reset both TEMP and TMP to their default (c:\Temp) restarted my system, and everything installed fine.

To locate and make sure TEMP and TMP are set to the same directory, perform the following steps:
1. Right-click on My Computer,
2. Select the Properties option from the menu,
3. Click the Advanced tab,
4. Click the Environment Variables button toward the bottom of the window.

I did this based on a Google search; didn't work.

If anyone knows anything about this problem I need your help please!

I FOUND MY FIX!!!

So simple yet easily overlooked! The fix is to ensure that all files and folders are NOT set to "read only"! Can you believe that? I set all of the program files and folders, temp folders, etc. on the c drive so that they were not read only and viola, all installed and ready to go!

Hope I can help someone else who may be having this problem.

Now that I have no hair left, here's a solution that finally worked for me....

You must make sure that the Windows file "mdmgen.inf" exists in the \windows\inf folder. Setup creates a generic modem "Standard Modem" in Device Manager and binds it to one of the COM ports for "RIM Virtual Serial Port"

For whatever reason, I didn't have mdmgen.inf on my laptop with HP OEM install of XP-SP3.
