Hi SCode,

It's probably just me, but my VNC Manager can not detect any Citrix ICA Clients across our network.

We use Citrix across our entire company, all users and computers have the ICA Client installed, and all users use Citrix for 95% of their application.

When I perform an 'Update Registered Computer Status' it just shows up as a red icon.

When I try to connect I get this error;
Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

More details on a specific case.;

My computer;
Windows 7 Ultimate 64-bit
VNC Manager 6.0.23.0 x64.

Remote comptuer;
On local subnet
Windows 7 Pro 32-bit
ICA Citrix Online Plugin 12.0.0.6410

VNC and Remote Management works perfectly, just the ICA connection.

I've also tried to connect to remote computers with various OSs (XP, 2000) and ICA Clients (12, 11) all with the same result.

The only thing that is consistent, my computer is x64 with x64 version of VNC Manager, all remote computers are x86.

Hope this helps!

It would be great to get this to work, it would be an amazingly useful tool!

Thanks

Regards,

I was able to reproduce the problem using the 64-bit build. The 32-bit works just fine.

Only the built-in viewer is affected by this problem. The detect server status feature seems to be working just fine regardless of the bitness.


With regards of the problem with the 64-bit build. It looks like the Citrix Online Plug-in Web setup program installs only the 32-bit version of the Citrix ICA client:
http://www.citrix.com/English/ss/downloads/details.asp?downloadId=2304987&productId=186&c1=sot2755&c2=ost12713#top


But the 64-bit of the VNC Manager can use 64-bit ActiveX controls only. So it requires the 64-bit version of the Citrix ICA client to be installed.
I couldn't find download for the 64-bit version of the Citrix ICA client. Does it exist at all?! If you manage to find the download link please post it here.


As a temporary workaround, you can install the 32-bit build of the VNC Manager.

Ah, that makes perfect sense!

As far as I'm aware Citrix does not have a 64 bit version of ICA, we only use 32 bit.

I've just installed the 32 bit version of VNC Manager, and it seems to get further.

It still fails when performing a 'Update Registered Computer Status' check.

When I try to connect to the server, it gets much further than before, but it still fails.

I'm presuming the port setting may be incorrect, but I have no idea how to check which port the ICA is using, or which port I should be connecting to.

Any ideas?

As far as the bitness issue, I understand the constraints here, and I think that this is a suitable fix, I'll keep using 32 bit VNCM for now.

Thanks,

Hi There,

My apologies, I've worked out how to check which port ICA is using.

It is set to 1494.

For your information, you can check this by visiting this article;

https://support.citrix.com/article/CTX655216

So now that it's set to 1494, I'm not sure why I can't get this to work?

Thanks,

Graeme Lucas

Please try to increase scan timeout value: Tools \ Options \ Registered Computers Status Check \ Scan Timeout.
This will affect updating of already found computers only.

To increase the timeout value that is used when you run a DSF scan you would need to open a DSF folder properties and change the timeout value there.
