Ah right, I thought perhaps there was a problem with them installing on XP. There was a whole batch of Office 2010 updates from Microsoft Update late last year that weren't signed as usual, and the installations all failed. However versions individually downloaded from the MS Catalogue were fine. Glad these are still OK as well!

... It is my understanding that even the SHA-2 only code-signed installers (standard/debug) will install and function OK on a fully updated XP SP3/Vista SP2 system, it's just a minor irritation though that the OS+user can't verify the validity of the code signature...

... And for my XP friends here, since the officially provided installer (.exe) won't launch under Windows XP SP3, I hereby provide the official (but hidden behind a mandatory Oracle account ) link to the extractable jre-8u251-windows-i586.tar.gz archive/package that XP users can use to manually update their JRE8 installation: (32-bit:) https://javadl.oracle.com/webapps/download/AutoDL?BundleId=242059_3d5a2bb8f8d4428bbe94aed7ec7ae784

I won, its working! Solution was never Nvidia bios. Gigabyte flashing utility, really hasnt too much options. So i tried Nvidia NVflash. When i tried it, i had problem that some Bioses refused to work because is BoardID - there are 2 variants of Geforce6600GT , ids 4300 and 4301. I found out that i need bios with ID - p216h1. When i tried Nvflash, i wasnt able to force bios, but i found that that olded Nvflash (5.93.0.1) has options to overcome it with -4, -5,-6 optimal parameters. Original bios was 5.43.02.27.00 when i searched through TechPowerUp bios DB: https://www.techpowerup.com/vgabios/?manufacturer=MSI&model=6600+GT I found that tehre is newer MSI bios (5.43.02.69.00) - https://www.techpowerup.com/vgabios/3163/msi-6600gt-128-050411-2 I flashed it to card and now its working.
