Mr. Mike Fogleman,

Thank you again.

The file type association between .dwg and AutoVue application has
been created.

Upon activation of a Hyperlink such as,

=Hyperlink("C:\Apps\East\ Glycol Reboiler Package\1061-L-DW-402-3
SHT.
2.dwg","Click")

AutoVue is loaded and the .dwg file opens.

However, there's System intervention via a dialog box that states,

"Excel.exe has generated errors and will be closed by Windows.You will
need to restart the program."

And there, Excel is forced to shutdown.

Please share your experience. Regards.
