I've seen Syncrosoft get confused with multiple dongles. Does GS4 launch with the Vienna Key pulled out? You can transfer the GS4 license to your Vienna key in License manager, that may solve your problem.

 Contact TASCAM support.

I just received GS4 this morning and installed it on a new Vista x64 machine.  The only dongle on this PC is for GS4; VI on a different machine.  Anyway, the program installed fine and the licensing went fine.  The license for GS4 is on the dongle, but when I launch GS4 it tells me it cannot find the license or the dongle.  Retry does nothing, and cancel gives me SYNSOACC.dll does not have the expected interface.

I just submitted a support ticket to Tascam.  Frustrating...

Here is the response I received from Tascam CS.  I've not been home to verify this yet.

There are two causes for that error:

1. there are two different filesSynsoacc.dll onto the PC

2. the version number of fileSynsoacc.dll and Synsopos.exe don't match

- please look in all Hard Drives for the file Synsoacc.dll and delete all files

Synsoacc.dll, which have been found....

Afterwards:

Here are detailed instructions on installing the Syncrosoft License

Control Center using the "parameter /o" (overwrite) installation in Windows

Vista:

1. Please uninstall the Syncrosoft LCC. To do this, go to the Start

menu in Windows, Control Panel, Programs and Features, and

remove

the Syncrosoft License Control Center entry.

2. Delete the folder 'Syncrosoft' from your Windows system partition

in the 'Program Files' folder.

3. Download the latest version of the Syncrosoft LCC to your desktop

download for PC, and click save.

4. Now start the command prompt by going to Start, Programs,

Accessories, and select Command Prompt.

5. Right click with your mouse on the Syncrosoft installer, and

select properties. Please note the path at "Location:"

6. Now enter this path into the command prompt, and add

SyncrosoftLicenseControlSetup.exe /o

\SyncrosoftLicenseControlSetup.exe /o

7. After entering this, press 'Enter' and the LCC will be installed

in "overwrite" mode

Unfortunately, this did NOT work.  I tried for a few hours deleting files, reinstalling, etc.  I cannot get this to work and it is quite frustrating.

Sergino,

I don't know if you've solved your problem yet. I have had the same error messages when installing GVI on a XP64 computer. But tonight, I was succussful in getting it installed.

I followed the removel process of Syncrosoft as mentioned above. Then I did NOT re-install syncrosoft LLC. Instead, I just re-loaded GVI from disk, which also contains is an older version of Sycrosoft LCC which is loaded automatically with GVI. As that was the only version of the LCC now on the computer, it doesn't conflict when GVI tries to access the license.

I don't know if GS4 ships with a pre-installed dongle licence, but this is the way GVI shipped so Tascam put the LCC on the GVI disk.

I haven't loaded any sounds into GVI yet, but so far, Sonar 7 (64 bit) is recognizing and launching GVI and GVI has not license issue -- so far so good. I'll test some sounds tonight.

Let me know what you've been able to find out.

Good luck.

Ok, just posting my update because it may help others with the same issue.

I updated the LCC to the latest version and things seem to be working. I can open both GVI and VE64 in Sonar 64 and load instruments. Next step is to hook up the sound card and see if we can get sound.

So, the initial thinking is that you load GVI first and let the older version of Syncrsoft LCC load from the GVI disk. Then update Syncrosoft to the newest version.

I have just bought an i7 machine running WIndows 7, and the same issue is happening to me - did anyone ever get this to work on WIndows 7? I am also running the VSL VE PRO, so can't go to an old version of the elicenser software.
