I wanted to uninstall Java from all the machines and install the latest one. There were sometimes multiple versions of Java which had to be removed. Some machines had both 32 bit and 64 bit Java versions. Here is the easiest batch script to uninstall any version of Java on the machine. There were scripts available but they did not delete 64 bit versions of Java and some very old versions of Java. Hence I modified those scripts to meet my need. set mycmd=reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall /s /f *java* for /f " usebackq delims={} tokens=2" %%i IN (`%mycmd%`) do ( msiexec /uninstall {%%i} /passive ) set mycmd=reg query HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall /s /f *java* for /f " usebackq delims={} tokens=2" %%i IN (`%mycmd%`) do ( msiexec /uninstall {%%i} /passive )

I was stuck in an application where I had to use the 32 bit source for both 32 and 64 bit machines. The application seemed to work fine, except the context menu option in x64 machines. I found a great post by David Vielmetter on his blog http://davidvielmetter.com/tricks/context-menu-issues-with-gvim-in-windows-7-x64/ and I was able to solve the issue. I think context menu many times create an issue in 64 bit machines and this is a good way to solve them (This is entirely my point of view). If someone has some better suggestions, they are most welcome to comment here. I too would like to learn more on how to create 64 bit context menu options.

WinMerge application has the same source for x86 and x64 machines. The application works fine when packaged in MSI for x86, but the same application will not work on x64 as the context menu option will not be visible. To get the context menu option, follow these steps: 1) Install the source on 64 bit machine and from INSTALLDIR, copy the ShellExtensionx64.dll file. 2) Register this Dll file and keep its registry information in a reg file. 3) The 32 bit version of this ShellExtension is ShellExtensionU.dll, hence make the component of this .dll conditionalized to be installed only on 32 bit machines. For this you can write the Condition as: (VersionNT32) 4) Create a 64 bit component and import ShellExtensionx64.dll and its registry in it. The condition to make this component install only in 64 bit machines is: (VersionNT64) 5) Also keep in mind to launch the application before taking a second snapshot of the application. This will include some HKCU registry keys which go in HKCU\Softwar...
