Window7 x64 wont let me install most programs

Hey everyone.

My computer recently has gotten this weird thing where it wont let me install a lot of programs. Programs such as Skype, Microsoft Visual C++ 2013 Redistributable (x86) 12.0.21005, Nvidia software updates and others. Apart from that sometimes it tells me I don't have permission to modify certain folders. This all started when I tried to clean my computer from this browser hijacker (yahoo virus) I used a few cleaning software but I'm afraid it may have altered or damaged my registry. I don't know what info you guys may need from my pc but if you let me know I will do my best to find it and post it on here. Any information would be greatly appreciated, thanks!


*edit* Another issues is I had microsoft office installed for a few years now and suddenly it wan'ts me to install again.

Hi Welcome to Seven Forums .... You need to fill in your System Specs ... The Link below will help you achieve this ..

System Info - See Your System Specs


What Software did you use for cleaning ?


Please do a System Scan and report back with the results...


SFC /SCANNOW Command - System File Checker

CPU: AMD Phenom(tm) II X4 925 Processor

Motherboard: AMD Phenom(tm) II X4 925 Processor

Bios: BIOS Date: 10/26/09 16:01:30 Ver: 5.05

Total Memory: 8.00

Usable: 7.99

HDD: (1) WDC WD10EADS-65M2B0 SCSI Disk Device (2) Generic- Compact Flash USB Device (3) Generic- MS/MS-Pro USB Device (4) Generic- SD/MMC USB Device (5) Generic- SM/xD-Picture USB Device

Sound Card: (1) High Definition Audio Device (2) Scarlett 2i2 USB

Graphics Card: NVIDIA GeForce GTX 275

OS: Microsoft Windows 7 Home Premium 64-bit 7601 Multiprocessor Free Service Pack 1



The results of the scan were: Window Resources Protection did not find any integrity violations.

However, was I suppose to run this in safemode?

The cleaning software I use is standard: CCleaner, Malwarebytes, AVG, Glary Tools, I was also recommended to use Combofix(I know this is very dangerous but it fixed the problem with the yahoo virus and only used it as a last resort because all else failed) and tdsskiller

No normal mode was fine ... What Software did you use for cleaning ?

Do you get any error message when you try to Install Programs ?

For Nvidia it just simply says install failed,
For Skype I figured it out I just uninstalled and reinstalled but before it was that I already had the latest version installed
For Microsoft Visual C++ 2013 Redistributable (x86) 12.0.21005 it was: Error 0x80070005
For some reason my microsoft office also wants me to reinstall it...

For Microsoft Visual, I had to go to safe mode to install and same with nvidia

Looks like a Permission and Installer issue ... Read the Link below .....
