Question & Answer
Question
We are able to install Data Studio (DS) 4.1.2 successfully but unable to uninstall the existing Data Studio 3.1.1. When uninstall Data Studio 3.1.1 from Control Panel, it raises an error message pop-up window and can not uninstall it. Here is the message: +------------------------------------------------------------------------- | Java Virtual Machine Launcher +------------------------------------------------------------------------- | X Could not find the main class: com.zerog.lax.LAX. Program will exit. +------------------------------------------------------------------------- How can uninstall Data Studio 3.1.1 where Control Panel uninstall process gets an error?
Cause
It is an known behavior/limitation.
Answer
It may be happened where two versions Data Studio 3.1.1 and 4.1.2 installed machine.
Here is an workaround. Please try to uninstall all products including Install Manager
(IM) then reinstall IM and Data Studio 4.1.2. Below are detailed steps:
1. Use IM to uninstall as many packages as possible.
2. Identify the packages that are still installed, and manually clean
them up.
Example on Windows:
- C:\Program Files\IBM\{IBMIMShared | SDPShared}
3. Delete IBM Installation Manager.
Example on Windows:
- Delete the IM install directory:
C:\Program Files\IBM\Installation Manager\
- Delete the AppData directory (IM Agent Data):
Windows 7: C:\ProgramData\IBM\Installation Manager
- Delete the Windows registry (regedit) entry :
HKEY_LOCAL_MACHINE\SOFTWARE\IBM\Installation Manager
- re-install IM
4. Reinstall DS 4.1.2 and other products.
