I was running a system upgrade for Junior Librarian today, and came across a couple of computers that refused to run the update provided by MLS.
After clicking the ‘Update’ button, you could receive the following dialog boxes:
Update: here err=53
and
Software Update: File not found: vb6stkit.dll (53)
To resolve this to install the update, you need to visit DLL-files.com and download vb6stkit.dll.
Open the ZIP file that you have downloaded and copy v66stkit.dll to the temporary folder (to open this, click Start, Run…, type in %temp% and click ‘OK’).
Click the Retry button on the second dialog box and the installation will continue successfully.
