Not a valid win32 application

It could be that the program is not designed for your operating system. See...

Are you doing a Dual-Boot? With a Separate Partition on the Primary HDD? I'm a bit confused? Are you doing a install on the Primary HDD and installing over the Win XP? Did you format the HDD? Or on a second HDD?

For RMTH2, make sure you have the 1.1 patch and try again. If it is still failing, copy Rmth2.exe directly from the install CD into the folder that has the same filename and overwrite the installed one.

For your RMTH3 issue, it is usually caused by older software not being able to find the temp directory. Try copying the setup files to somewhere like c:\temp and install from there or set your temp variable to c:\windows\temp instead of your profile temp folder.

Hi bconejarez,
Regarding that Error you just mentioned it is either the program you are installing is not compatible with windows or the programs can be just damaged but if it something brand new then most likely it is not a windows Program or application.
You can also tr and check for issue like your Anti Virus program try disabling your Anti Virus for a while then try re installing the program again see if the error will occur again, if the error still occurs then it is the program you are installing that is the issue.
If you think that it is not the issue then you can try to back up all your personal stuff then re install windows and try installing the program on the newly installed windows see if the error will occur if it does then you will have to get a new copy of that program which is Windows Compatible, or possibly that is not damaged.
What Application/program is this that is giving you this Error not a valid win32 application?
and what windows do you run on your Machine is it XP. Vista or windows 7 also is it 32bit or 64bit?.
Thanks I hpoe this can clear thing out on you concern.
Have a nice day, Thank you for choosing Fixya.

Sounds like you might have downloaded malware. Did you get it from www.skype.com ? or some other web site? Try downloading a new copy from www.skype.com (and nowhere else!)

Try booting to the server 2008 installation disc.

I also have Sim City 4 Deluxe edition, and the package came with 2 CDs. Which were, the download and installation CD, and the gameplay CD. Now if you put in the Game Play CD without putting the Download and Installation CD in first, then that message might come. And if not, then the Gmae Play CD might be damaged, you can try rubbing alcohal and blowing on the CD, but if that doesn't work, see if you still have a warranty and try replacing the CD.

Hope that helped!!!!! Please Rate!!!!!!

the software you downloaded is corrupt please try to download a another setup.
