Hi, I have only just purchased my windows 7 pc and I am trying to download various programmes, for instance itunes. The downloading is fine, however, when I try and install I get the following message everytime, which means I cannot download anything. Please help as this is driving me mad and i cannot get on with my work.

Which Windows, 32 bit or 64 bit?

In reply to: installing downloads

The Windows 7 OS, (Operating System), comes in two flavors, 32 bit or 64 bit.

Which do you have, and be sure to identify whether the applications you intend to download and install are compatible with the version you have.

my computer is 64 bits. I have tried downloading and installing both versions of itunes eg 32 and 64 bits and neither will install.

This "is not a valid Win32 application" is often caused by malware infection.

If you can, download, install, update and run separately both Malwarebytes' Anti-malware and SUPERAntiSpyware.

If you are unable to either download or install these scanner utilities, find another computer, (relatives or friends)to download the MBAM installer file and then burn, (copy), it to a CD or copy to some memory stick or other.

Then use that to copy the installer file to your computer.

If MBAM still will not install, change the name of the MBAM installer file to something else, like gogetup.exe and try installing with that. Once installed, run the MBAM scanner and perform a full scan.

If MBAM will not open, you may have to change the name of the mbam.exe file in the Program files folder to gogetum.exe or similar then run it from there.

If none of that works, reboot the system into Safe Mode and try again.

MBAM should have sufficient definitions in it to perform an initial scan, but once that is done, make sure you can then use it to update it's definitions and perform another full scan.

Then install, run, update and scan with SUPERAnti-spyware.

I hope that helps.

Hi Mark

Thank you for your advice on how to resolve my situation. I have successfully downloaded both the programmes you suggested. I have run a full scan using both programmes, restarted my computer and tryed to install the programmes I have downloaded, eg itunes and still getting the same error message. I have also been told that if I installed google chrome I would be able after all to install itunes, however, i am still in the position I was when I first posted my question to you.

P.s. I have downloaded every version of itunes there is, eg 10.1, 9 and so on for both 32 bit and 64 bit windows 7. I cannot understand why I am not able to install.

Hope you may be able to suggest another option.

There's a clue in your post.

Not much of one but I'll use it.

When I download the files here go to:

Yours appear to go elsewhere. I wonder if your machine has any download accelerator or manager. Look around and tell the forum why the downloads folder is not stock.

I know that later in this discussion ...

you indicate you have downloaded and tried "every version" but since the error message stating " not a valid Win32 application." is generally either caused by malware, file corruption, or not designed for the specific OS I have to ask if you might be using a download manager of some type (download managers are often associated with corrupt downloads) and if so if you have tried downloading without it?

If no download manager is involved try FIRST deleting the ones you did download then downloading the same applications from a second source such as here -

Also, try downloading the application on another PC then using either a CD or a USB flash drive to attempt to load it on the problem PC. If it installs properly this verifies either file corruption or possibly (based on the path you provided) a permissions error.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
