How to fix the " "The Miroslav Philharmonik 2 Sound Content (1 of 16) installation failed. Unable to copy the instruments" error message "
The issue is that the folder where your soundbank is stored and the folder from which you are installing from is too long of a path name. Just a quick explanation of what I am talking about before I explain the fix;
Quoting from http://vimalsuresh.com/2013/08/08/how-to-fix-file-path-too-long-error-while-copying-deleting-or-opening-files-without-using-third-party-applications/ "There is a pre-defined character limit beyond which you cannot name a file or folder, and it varies from one OS to another. Mostly it varies between 256 and 260 characters. This is the character limit for a file name, which excludes the file path under which it is located, like “C:\Documents and Settings\Test User\Desktop\test file.txt”. But, when you copy a file from one location, it takes into account the entire file path. So, if the file is residing under a folder which is too deep or too long, that has a length beyond the set-limit, you will get errors like the ones shown above."
The fix is quite simple, shorten the names of the folders/move your sampletank3 soundbank into a folder with LESS subfolders
Examples:
C:\Documents\User\Desktop\SampleTank3\... move to C:\Documents\User\SampleTank3\...
or
C:\Documents\User\SampleTank3\... rename to C:\Documents\User\ST3\...
I hope this helps,
