DPlot

When I install the latest DPlot (version 2.3.3.9) on my XP PC, the following errors pop up during the setup:

1) Microsoft Visual Basic
Run-time error '13'
Type mismatch

2) Error
C:\Program Files\DPlot\addin\DPlotLIB.XLA
An error occurred while trying to read the source file:
The process cannot access the file because it is being used by another process
Click Retry to try again, Ignore to skip this file (not recommended), or Abort to cancel installation.


Any idea what's the problem?

Both are related to the Excel Add-In. Check to make sure Excel isn't running (and also that there isn't a dead copy still in the Processes list w/ Task Manager. (Sorry if this is obvious, but press Ctrl-Alt-Del, select "Start Task Manager", click the Processes tab. If you see excel.exe, kill it.)

If this is no help please let me know what version of Excel you're running.

No. I didn't have Excel running in the background.
I realize it's Microsoft Lync that causes this problem. I need to terminate it before a successful installation.

Thanks for the info - I never would have guessed that. I'm not familiar with MS Lync but will look into how to determine whether it is running programmatically so that the setup program can throw up a warning.
