|Subject||RE: [firebird-support] Problem with GTT, Firebird 2.5.4 64 bit|
I had similar problems in the past and the culprit was with the TEMP directory locations.
I would check in the firebird.conf where the Temp directory is set to.
I would also check the TEMP and TMP variables and see where they are pointing to.
Do you have a C:\TEMP on that machine?
I hope this helps
