OUI starts and after prerequisites check, OUI crashes

From java trace file:

Unexpected Signal : EXCEPTION_ACCESS_VIOLATION (0xc0000005) occurred at PC=0x80D7A9C

Got this problem on client workstation (win2000prof). Initially we have attempted to start oracle iODS installation, but installer crasged just after prerequisites check by firt ‘next’ button pressed. Then I’ve checked if is possible to start oracle client installation, but things got even worse, installer crashed just after prerequisites check completed with OUI wondow showed up for 1 sec.

What I have checked next with no luck:

  • user is in administrators group
  • path variable less than 1024
  • windows2000 sp4
  • installation folder is simple c:\install
  • we tested to install just after complete restart (no apps running)
  • no other oracle services running as system services
  • no problem with installation packages (tested on my own workstation)

Ive even suspected CPU issue, on this workstation new core2duo cpu (I still remember problems with installer on
Pentium4 😉

With help from oracle support, problem been resolved by removing unused oracle entries from windows registry (unregisted in oraInventory entries)

CAUSE: Windows registry seem corrupted on the Oracle branch
