I received an e-mail from HCL Support (IBM) about a problem with the interin fix.
The e-mail and later a call from the support told me to download the fix again and if in case i was installed the fix how to remove and install the good one.
The problem was with the fix files from last week. The files was updated with the ones above.
“I would like to notify you because we found a problem with this Interim Fix. The problem discovered and that the fix can’t be uninstalled properly, which can cause problems later when a new hotfix or interim fix is applied on him.”
