I have installed VS2010 SP1 with .NET 4.0 and cannot find where the microsoft.office.tools.excel.dll is located.
Question> Where I can find this DLL?
Reinstalling the program may fix this problem. office. dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vender for support.
A DLL is a library that contains code and data that can be used by more than one program at the same time. For example, in Windows operating systems, the Comdlg32 DLL performs common dialog box related functions. Each program can use the functionality that is contained in this DLL to implement an Open dialog box.
Normally this assembly should be in the GAC once you install the Office Primary Interop Assemblies assemblies. On my computer the assembly is located in:
c:\Program Files\Reference Assemblies\Microsoft\VSTO40\v4.0.Framework\
And here's the corresponding article on MSDN about installing those assemblies.
