I have had a right ball-ache today trying to get TM1 Perspectives and Architect onto an XP workstation computer.
What should have been a very straight forward installation was complicated by what turned out to be a "dirty PC".
There is not really any need to cover the actual installation of Perspectives or Architect here as its a very basic Windows Installer, but when it goes wrong it does so seemingly quietly.
The first error message that I encountered was as follows:
The wizard was interrupted before IBM Cognos TM1 could be completely installed.
Your system has not been modified.To complete installation at another time, please run wizard again.
This was quite frustrating, I run the installer several times, I rebooted the computer and installed Windows and Office updates. Nothing seemed to make a difference.
Looking in the Windows Event log didn't offer up any useful clues either. So I decided to embark on a bit of detective work.
In the %temp% folder I found a log file called IBM_TM1Install.log - a rather large file which surely would contain the answer SOMEWHERE!?!
To my relief it did, a useful error:
The TM1 installation was unable to create a backup copy of the previous TM1 Web files on your computer. To continue, do one of the following: Stop any Windows services or programs that may be locking the TM1 Web files. Or, select a different installation directory for the new TM1 Web files.
Well, it would have been a useful error, had I actually had TM1 Web or in fact ANY previous version of ANY TM1 software installed. The trouble is, I had never installed anything to do with TM1 on this particular computer.
This led me to take a punt and assume that it had found some sort of Cognos related files somewhere on the system. First thing to check "Program Files", nothing there.
So next I checked the registry. Bingo! There was a Cognos entry under HKLM\Software and HKCU\Software. Further investigation showed that these were related to a previous installation of the Cognos Planning client. As they were no longer needed I deleted them and tried the installation of TM1 again.
Great news, this time it worked a treat. And then it broke again. At least it had the decency to offer me a new error to play with.
Error 1609: An error occurred while applying security settings. ASPNET is not a valid user group. This could be a problem with the package, or a problem connecting to a domain controller on the network. Check your network connection and click Retry, or Cancel.
Oh lovely, an error that could mean anything. It didn't take much googling to find an answer though. The installer is expecting to find ASP.NET, or rather an ASP.NET account. I was quite pleased at finding this information as it seemed to be an easy fix... if it worked.
Create the following:
User Name: ASPNET
Full Name: ASP.NET Machine Account
Description: Account for running ASP.NET applications
Password: [whatever you decide]
set: User cannot change password and Password never expires.
I hit the retry button, it worked!
Ok, so thats not really a very dramatic ending but thats what pleased me the most. After spending around 3 hours messing around with it, it finally installed.
