Windows Installer Error after downloading Adobe Elments 9

I downloaded your Adobe Photoshop Elements 9 about ten days ago and immediately after downloading I received two  Pop UP  problems that I have been unable to resolve.  One of the problems Is 1) I get a "Windows Installer"  popup each time I start my computer and 2). Windows

Hoist has stopped working.

I have researched all resources and find the only solution is to wipe my computer clean and reinstall everything.

My computer is a HP Pavillion dv8000, Windows Vistaa 32 bit, SP 2.

Please advise if you  or any other member has efxperienced a similiar problem.

Thank you in advance for your help in this issue.

Sincerely,
