Excel not recognized in XLPack Addon Manager
[Q] When XLPack Addons is installed and XLPack Addon Manager is started, even though Excel is installed, "Unable to verify installation of Office (Excel)" is displayed in the system information.
[A] Whether or not Excel is installed is determined by whether EXCEL.EXE program exists in \Program Files\Microsoft Office\root\Office16 or \Program Files (x86)\Microsoft Office\root\Office16 on the system drive. If it is installed in other special location, Excel will be recognized as not installed. Even in such case, processing will continue and the license will be set normally.
However, please note the following known issue.
