Add-in causing very slow loading in Visio

I have discovered an interesting side effect - my addin to Visio 2010 was causing 40+ second delays. Easily verifiable as just the action on Developer > COM Addins and checking the adding box caused a major delay.

Fr om various forum searches I tried a few things, including .Net 4.0, disabling anti-virus etc, but nothing really changed.

From using Procmon, I realised that there was a major time period wh ere Visio did not appear (i.e. was "paused") and immediately at the start of that period, there were calls to print related services.

My default printer has some form of network problem and can be very slow to load. By changing the default printer, all the problems went away.

I am not sure why the addin interacts with the default printer in this manner??

Loader version: 6.6.3059.0
Operating System: Microsoft Windows 7 Professional Service Pack 1 (build 7601), 64-bit
Process Owner: Administrator
Command Line: "C:\Program Files (x86)\Microsoft Office\Office14\VISIO.EXE"
Run 'As Administrator': No
Process Elevated: No
Integrity Level: Medium
UAC (User Account Control): On

Hi Robert,

First of all, please check out the http://office.microsoft.com/en-us/office-2003-resource-kit/how-office-performs-certificate-revocation-HA001140308.aspx settings on the PC. Is it enabled on your PC?

Anyway, I have found a lot of similar forum threads for you:

I have a workaround - set a different default printer.

But why does loading the addin cause the printer to be checked?

Hi Robert,

The printer shouldn't affect COM add-ins registered for Visio. Anyway, it looks like the issue depends on the host application. Do you see any delay in the adxloader.log file?

BTW Did you have a chance to check the Certificate revocation settings?

Hi Eugene

I checked the Certificate Revocation settings and turned them off - didn't make any difference.

If I set the default printer to the slow printer and start Visio without the ADX addin, it starts within a few seconds. With the ADX addin it takes 25-40 seconds.

If I set the default printer to e.g. Send to OneNote, and start Visio WITH the ADX addin it starts only a couple of seconds longer than usual.

No delay in adxloader.log visible.

Hi Robert,

Are you able to reproduce the issue with a newly created empty add-in project? Did you try to create a VSTO based add-in project? Does it work as expected?
