None of my programs work, cant install or uninstall

[AdamJohnson36]

I have a hp pavillion dv6 laptop that is a few years old. I am running Windows 7 home premium 64bit. When ever i click on a program, nothing happens. i am unable to install or uninstall anything. I do have avast antivirus installed, but i am unable to uninstall it or any program. i also cannot download anything, after a file is finished downloading nothing happens. Does not save to computer or open. Only my internet works pretty much but cant really go on youtube becuase i need adobe reader which i cant install. tried the scannow thrice in the elevated command prompt, didint work. Any help or ideas would be greatly appreciated.
Thanks

Hello Adam, and welcome to Seven Forums.

You might see if you may be able to download and merge the .reg file for the listed EXE option in the tutorial below. It will restore the default associations for .exe files, and hopefully help.

​

In addition, I would recommend to use Windows Defender Offline to do a full scan of your system at boot to help make sure that your system is clean. If need be, create it on another 64-bit Windows to use on your system.

Hope this helps,
Shawn

Do you still have any Recovery discs?

Is the Product Key on the laptop base clear enough to read and copy?

Is there stuff on the lappy that you need? (Files, folders, Photos, music, videos etc.)

Can you transfer these to an external source? (External Hdd/another PC/DVD's, whatever.)

I have a 3+ years old DV7 and I recovered all my stuff to a USB key and Double-layer DVD, before writing down the Product Key and using another Win7/64 bit disc, to carry out a fresh install of Windows. Then I reinstalled all my programmes and other stuff.

This has the added bonus of removing all the HP software, which is frankly garbage. It speeds up your machine, if the Hdd and all other hardware is OK it will seem like a new lappy.

I think as a precaution you also need to look at a possible infection. If you get it back to working order, download an Internet Security product, check with Malware Bytes. Even Microsoft Security Essentials will help.

EDIT:
I wrote this post before seeing the others - follow their advice FIRST.

SOrry i didn't think about that . m a fOOL

how can one install and run a program if installer and .exe are not working

 

[AdamJohnson36]

still not working. I dont have the recovery disks might look into that

Any clues as to why its not installing/uninstalling?

 

[Brink]

Did you already try what I posted above to restore the default associations for .exe files?

 

[AdamJohnson36]

Yes its still doing nothing. I ran the Windows Defender scan and it didnt show any errors.

In that case, you might see if you may be able to do a system restore at boot using a restore point (if available) dated before this issue to undo and hopefully fix this.

A few years old and no disk image created ????

Can you generate a System Repair Disc - Create?

If not download and burn to DVD or write to flash stick the installer provided in Clean Reinstall - Factory OEM Windows 7.

Boot into System Recovery Options to run System Restore to a point before the problems began.

If this fails try running SFC -SCANNOW Command from Win7
or if necessary SFC -SCANNOW Run in Command Prompt at Boot.

If these fail try using the provided installer to run a Repair Install.

If this fails then run Factory Recovery from Windows or using the hotkey at boot: HP Recover Windows 7 Operating System Using HP Recovery - HP Customer Care (United States - English) or run the superior Clean Reinstall - Factory OEM Windows 7.
