Uninstallation problem

When program is installed it is fired(by the installer) right after installation finishes. But when i uninstall the program from Control Panel, then it tries to open the exe too, which gives the following error:

Windows cannot find 'MyExe.com'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

with the cmd.exe in the background. after i press OK, another window pops up, saying:

There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support...

Although the program gets uninstalled, these errors are not desirable.

Also when i install newer version and older version of the program already exists, i get similar messages as the installer tries to uninstall older version first.

Here is the code:

....

<Property Id="PREVIOUSVERSIONSINSTALLED" Secure="yes" />

    <Upgrade Id="D2B0D435-0F86-4D5E-A988-B24215882***">  
      <UpgradeVersion
        Minimum="1.0.0.0" Maximum="99.0.0.0"
        Property="PREVIOUSVERSIONSINSTALLED"
        IncludeMinimum="yes" IncludeMaximum="no" />
      </Upgrade> 

    <CustomAction Id="LaunchApp" Directory="INSTALLDIR" ExeCommand="[SystemFolder]cmd.exe /C start MyExe.exe" />

    <InstallExecuteSequence>
      <RemoveExistingProducts Before="InstallInitialize" /> 
      <Custom Action="LaunchApp" After="InstallFinalize" />
    </InstallExecuteSequence>
  </Product>
</Wix>

What i would like, is that installer would try to run the program only when installation occurs and do nothing when uninstallation is processed.

Thanks in advance!

Your problem is that you don't have a condition on the action so it fires every time. At a minimum you need a condition of "Not Installed". However for a more elegant solution, read:
