I shut down Visual Studio and uninstalled manually with Add/Remove Programs, first the help and then the add-in.

Then I started Visual Studio again. Before loading a solution, I see one TeamCity menu still there, with menu items in it (not duplicated). I then tried to load the same solution again. I got this dialog:

Microsoft Visual Studio

Package Load Failure

Package 'JetBrains.TeamCity.Package.TeamCityPackage, JetBrains.TeamCity.Package, Version=1.0.3811.3811, Culture=neutral, PublicKeyToken=null' has failed to load properly ( GUID = {D7EB1F36-1BCF-4427-8BF1-F47B0B3862E9} ). Please contact package vendor for assistance. Application restart is recommended, due to possible environment corruption. Would you like to disable loading this package in the future? You may use 'devenv /resetskippkgs' to re-enable package loading.

Yes No

I clicked No. The solution loaded, and the TeamCity menu is there, with all menu items enabled, but clicking them does nothing.

I exited Visual Studio and loaded again. It went exactly the same way, except this time I clicked Yes. Same results, TeamCity menu is still there and items do nothing.

Exited again, started up again, opened Add-In Manager and unchecked VSSDK.VsIdeTestHost and its Startup box, OK, exit, restart, but the menu still appears.

Looking in the registry, I find this:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0Exp\Packages\{26c61dac-f2bf-44ff-849e-222371c246ae}]
@="JetBrains.TeamCity.Package.TeamCityPackage, JetBrains.TeamCity.Package, Version=1.0.3914.3914, Culture=neutral, PublicKeyToken=null"

"ID"=dword:00000068
"MinEdition"="Standard"
"ProductVersion"="2.0"
"ProductName"="TeamCity Integration"
"CompanyName"="JetBrains s.r.o."

and this:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0Exp\Packages\{d7eb1f36-1bcf-4427-8bf1-f47b0b3862e9}]

with the same ID but a different ProductVersion and GUID.

This second key {d7eb...} appears also in the 8.0 section, but the first one does not:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Packages\{d7eb1f36-1bcf-4427-8bf1-f47b0b3862e9}]

Is it a safe workaround to manually remove the above keys from the registry, to be able to cleanly install the 3989 add-in?

Thank you!

That is the known issue for TeamCity VS Plugin installer.
To fix the problem, please use the workaround

 - uninstall TeamCity plugin from Add/Remove programs applet, 
 - install older version of TeamCity addin and uninstall it (if you do not have one I send it for you). 
 - install latest TeamCity VS plugin. 

That workaround should solve the problem.
The problem was in the intaller which was, unfortunately, unable to uninstall
previous version of the plugin before installing new one.

Thanks Eugene.

I do have the 3914 installer still, but not the 3811 installer (the registry keys show that there are remains of both of these versions). Do I need to install and uninstall both of these old versions? Could you make the 3811 installer available?

Removing the above registry keys is not enough?

I've installed 3914 and uninstalled it again, but regedit shows that the 3914 registry key (as shown above) is still there in registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0Exp\Packages\{26c61dac-f2bf-44ff-849e-222371c246ae}

... is that expected? Do I need to install and uninstall first 3811 and then 3914?

I found the TeamCity 3811 installer on my disk and extracted the add-in installer from that.

Installed 3811, uninstalled 3811, installed 3914, uninstalled 3914. Registry keys are still there, TeamCity menu is still there.

Oops, sorry, a bit too fast there ... TeamCity menu is gone now, and although the registry keys are still there in 8.0Exp, the one that was in 8.0 is gone. Trying 3989 addin now.

Add-in version 3989 installed without problems, and correct number of menus appears (i.e. 1). But "Open My Changes Window" threw up an exception like before (see http://www.jetbrains.net/jira/browse/TW-2174 ) --- is that unrelated to these installation problems?

Please, try this one. Problem should be fixed.

To install patch, please close VS. Extract all files to the installation folder with overwrite.

Hope this help

Minor cosmetic issue: on VS startup (before loading solution), all menu items were enabled. I tried Open My Changes Window, and it very nicely opened and told me to open a solution. After closing it, all menu items were disabled, except Login. I tried that, and it also told me to open a solution. The cosmetic issue is that all menu items (and maybe the whole menu) should have been disabled to start with.

On loading the solution, I get a dialog saying this:

"Team City Integration is outdated. Please download and install new version from the current TeamCity web server."

offering the buttons Download and Cancel. I click Cancel. In the TeamCity menu, all options are disabled except Login. I try Login, it gives me a login window correctly filled out with previous values and I click OK, but it gives me the same dialog as above. I click Cancel again, and now I get a new dialog with the following:

TeamCity Login

TeamCity Visual Studio addin version is incompatible with server. Please download new TeamCity Visual Studio addin from TeamCity server.

OK

So the add-in is currently unusable because of the version check.

(To clarify, the previous comment was to describe the results of testing the updated plugin that you attached)

I'm sorry, that was my mistake to send you version of plugin for new version of server ( I mean server protocol version).

We plan to publish TC 2.0 Beta today. This version will contain fixes to that issue.
