Just came across the below-appended post. Loathe as I am to poke around in the registry (especially with a new-to-me-OS), I'm seriously considering trying it.
I wonder why they refer to the "64-bit version of the syncrosoft/eLicenser" since, as I wrote above, there is only a single file available for download, which was automatically installed into the (x86) folder of my 64-bit system...???
Anyway, here's the post:
The 64-bit version of the syncrosoft/eLicenser driver has the syncrosoft information that GVI is looking for in a different registry location than the 32 bit version of the driver, so when GVI goes to look for it, the info is not there.
The 64 bit registry location is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\SynUSB64\Enum
...whereas GVI is looking for...
This latter entry therefore needs to be created, and contain the same values as what is in the former entry.
To do this, Click on Start>RUN>type in regedit
Navigate to the following registry location:
Right click on the SynUSB64 folder and select export to export this particular registry key to a .reg file. It doesn't matter what the name of the file is as long as it has the .reg extension. Save the export to a location easy to find such as the Desktop.
Right click on the exported .reg file on the Desktop and select Edit.
Change every instance of the word SynUSB64 to SynasUSB
Save the file. Then double click on the .reg file on the desktop and it will import into the registry.
You can check the registry to see that the following key has been created along with the folder structure identical to the SynUSB64 key:
