ZWCAD is not a valid win32 application

Asked By 200 points N/A Posted on -

I installed a freeware ZWCAD installer trial version a free download in the net. As the installation was finished this message appeared on the screen


D:Setup.exe is not a valid Win32 application.

Because of that error I decided to stop the installation and removed from the control panel. As I go on to my next installation and this time an Adobe Photoshop Cd installer. When I started to install the said software and finished the setup cannot be open and the error came out again.

I did the restart options to verify if the installation is completed but still the error is there.

How on earth can we remove the so called error?

Can you identify the problem?

Please help thanks!

Most likely when we try to install some application and launch its executable file we may see an error that is showing a message like “invalid Win32 application. ” More specifically an error like “C:Program FilesProgram FolderProgramName.exe is not a valid Win32 application". This can be caused by a corrupted file or missing some associated files that needs to execute the program or the program that you installed is not compatible to your current operating system or most likely a compatibility issue on your hardware.

If the file that you downloaded is corrupted, then your operating system is unable to run your program correctly. Download the file again and double check that your download has completed successfully and that is compatible to your operating system.

Uninstall the previous installation of your program before you install the newly downloaded file. Maybe when you downloaded the file it became corrupted during the downloading process. If redownloading of program won’t work then try to download the file from a different source. The program might be corrupted before it was uploaded.

If your hard disk has been corrupted it may cause the program not to execute properly because some part of the program or data are unable to read by your hard drive. Perform a scan disk to your computer and also defrag your hard disk. This may correct any error in opening your program.

If a program is not compatible to your operating system then you will encounter this error. Although some programs when installing it will prompt you that it is not compatible for your current operating system. Also if the program is designed to run only on a 64 bit Windows and you are using a 32 bit version of Windows then you will also encounter this problem.

A wrong configuration to IDE controller can also cause this problem.

Right click on My computer on your desktop>>>>select “Properties” Under the “System Properties”>>> select “Hardware” tab >>>>click the Device Manager>>>> Double click the controllers named IDE ATA / ATAPI>>>> click on the Primary IDE and Secondary channel. Under the “Advance Settings” and on the Device 0, make sure that DMA is the default setting.

If the file is unregistered then you have to register the shell32.dll on the registry. To confirm, open the command prompt by clicking the Start menu>>>> Run and type cmd and press enter. On the command line type regsvr32 / i Shell32.dll

In some cases this is most likely caused by a virus, Trojan or other Malware. Your Antivirus is restricting you to open that file because it contains a Malware. Try to run a scan on the file and see if it is infected by some Malware. If no virus was found it is possibly that your Antivirus is affecting the installation process of your program. To address this issue, reboot your computer and start on a safe mode, then install the program again. After installing it, restart your computer in normal mode and see if it fixes the problem.
