Error 2753

Your having trouble installing HP Wireless Assistance. The aftermath after or during the installation is getting an error code saying what exactly?
I need to determine if the error is from Windows, from HP installation software, or something else.

When did it started happening, if it was recent, we could easily try system restore.
To me you seem to be trying to install wireless drivers?
Please update your computer specs.
System Info - See Your System Specs

I can assist you with a complete uninstallation and remove of your wireless driver, and help you reinstall them.

Or someone else will, im soon to head off to bed

You still haven't told us what your computer specs are, i need this information so that i can link you to the correct wireless drivers.

Anyways please use CCleaner,
Download CCleaner 3.16.1666 - Download - FileHippo.com
Run the registry cleaner, it will check for empty entries or leftover entries. When you run it it will ask you if you would like to make a backup please do so.

Fix problems with programs that can't be installed or uninstalled
This tool is the replacement of the utility mention on page 1. Please run it and follow the instructions.

RE-DOWNLOAD and save the wireless drivers, and run it.
Make sure you are downloading the correct driver for your wireless card, and for the right operating system.

Is your computer a laptop by hp?
if so click
Click Computer
Click on System Properties (see attachment one)
What Model do you have ? It should say detail information about your manufacturer and model.

Or you can look underneath your laptop their should be a sticker saying model number. See attachment 2

Second post:
Also have you done Windows Updates, make sure .net framaework is fully updated and installed. A lot of games/programs rely on this and this can sometimes lead to installation problems or programs cant update.

One possibility is that the software is not compatible, your downloading Drivers for Vista and not 7. They do not have support for Seven.

Update post:You could try installing the program under compatability mode. Maybe this will allow for your installation to go without error.
Compatibility Mode

If you would like to retry, i suggest completely uninstalling all of Microsoft . Net Framework, rebooting.
Re Do windows updates.
Reboot.
Try to install the drivers again.
If this does not work, maybe someone else has a better idea.

2 suggestions off top of my head
-Revert and install vista
-Buy a Wireless USB adapter

Internal Error 2753 when installing WinZip - WinZip Computing :: Knowledgebase

Yes, I know that is for WinZip, but the same principle should still apply.

Try using something like Revo Uninstaller Free and see if it can remove the remnants of the previous installation(s), then give it another shot. :)
