Today I faced an issue, I want to open an excel file from a Windows application; before opening the file, I want to verify that MS Excel installed on the system. I found a solution using registry from MSDN.
Here is the code snippet.
But the problem with the source code is I need to know the office versions, and can identify exactly which versions are installed.
And here is the office version information.
I don’t want to know the version of the excel installed. I just want to open a XLS file created by the application. Later I found another code snippet which will return whether Excel installed or not. Here is the code snippet.
