Greetings all! I thought I would post this here and see if anyone had any ideas before I am reduced to wiping my drive and starting with a fresh install of Vista. The problem is this. I am trying to install a Virtual CD program that is, according to their site, Vista compatible. However, the installer quits before all the files have been uncompressed with the error -5006 : 0x800700b7. Ok, so maybe their installer got corrupted and won't work. I tried another Virtual CD program that I had demo'd earlier and then uninstalled. Though the installer ran fine before this time it won't install with numerous errors about being unable to open CAB files. So later in the day I try and install a game (Clive Barker's Jericho) and get the exact same error (-5006 : 0x800700b7) . I look up the error on the net and the results are, in the majority, that my registry is corrupted and to use some program like RegCure (which I've done without any positive effect.) Any ideas? Here are my specs: Windows Vista 32bit, with all updates current from the date of this post. AMD Athlon 64 X2 Dual Core 6400+ 3322 MB RAM (as logged by dxdiag) MSI K9A2 Platinum Motherboard ver 1.0 Default System BIOS NVidia GeForce 7900 GTX Soundblaster X-Fi Extreme Gamer Fatal1ty Pro I'm happy to offer any more information if needed. Thanks!
