Hello,
I installed PostgreSQL since HM1 long time ago. Today I reinstalled my Windows 7 64bit and can not install with your new combo installer (with PostgreSQL 8.4) with the error could not install PostgreSQL.
I tried installing standalone PostgreSQL then newer 9.1, disable firewall, add exception, uninstall Avast but still no luck.
I kept Google and found someone mentioned that there are some errors in newer PostgreSQL installers and I fall back to 8.2 and it installed on my Windows 7 64!
Now my HM2 is running with PostgreSQL 8.2 but I cannot restore my old backup. Is it normal for HM2 to run with 8.2?
Please help!
