Project could not be opened because Microsoft Visual C# 2008 compiler could not be created. ...

Question

... QueryService for '{74946829-37A0-11D2-A273-00C04F8EF4FF}' failed.

 

I see the message window with this text on my screen every time I try to open project in C# 2008 express. The same for new or any other project of any kind ;-). I tried to reinstall C# 2008 express few times, with the same result.

On property page in tools->options->Windows Form Designer I can see 'An error occurred loading this property page'

C++ 2008 express works fine.

Any idea??? 

Thank You for help in advance

Answer 1

;-) nobody help me -

 

I found in my registry

HKEY_CURRENT_USER\Software\Microsoft\VCSExpress\9.0\Packages

 

that there are 5 registry entries (class GUIDs) with key 'SkipLoading' set to DWORD value 0x00000001

 

I changed the value to 0x00000000 and now C# 2008 Express is working as expected ;-)))

 

Yes, it seems very easy to understand ....  I am happy now and I can continue to work on my own business. What I really don't understand is why the installer wrote the value 0x00000001, because I checked the registry before (no such values where there). It is very funny!!!

 

Thank You Bill for self explaining name of the property ;-)))

Answer 2

I had the same problem, and doing that fixed it, well, half of it. Now I am still unable to load files. I can create them fine, but I can't add to project or anything. Any ideas?

Answer 3

Actually, I just fixed that... Rename 9.0 in the registry to something so that you can remember it (I set it to "Hello (9.0)"),
then when you start, it will automatically create a new one, and the settings it created fixed it!

Answer 4

Thank you! That solved the problem.

Answer 5

I was having the same problem with visual studio 2008 and by changing the dword values for each skiploading key I was able to get my projects to load.

 

Answer 6

Cara, que coisa mais louca! Mas a sua resposta me ajudou muito. Obrigado

 

Answer 7

Not only was the guid key missing but I had to change the skipLoading to 0.

Thank you guys. my job was giving me a lot of ***.

Answer 11

Hello,

 

Like the above posts this did fix my problem.  My question is why does this fix the problem and what made you think to look in the registry and change some values?  I would be interested in the technical details to the solution.

 

Thanks

 

Answer 12

I found easer way.

devenv /ResetSkipPkgs

Answer 13

Fantastic! Works for 2005 as well. Thanks a ton!

One detail...

My VS 2005 stoped working when I installed 2008. 2008 was working fine though. I uninstalled 2005 but could not wait untill SAs reinstall it, so installed 2005 C# express. I saw that mentioned by someone else..

 

Anyway, THANK YOU!

 

Answer 14

Thanks a lot, that solved my problem!

Chris

Answer 15

I had the same problem, and I tried the following at the VS 2008 command prompt, and I was able to open and compile solution files.
devenv /ResetSkipPkgs

Answer 16

I had this problem this morning and did a search and found this forum!

Just as I was about to open regedit, a message came up saying "update complete would you like to restart your computer?"

I said no, but tried loading the project again and Voila! it loaded!

So in some circumstances it could be that windows is doing and updating whilst you are working.

Answer 17

That was back in 2007...and this trick still works in 2008! Thanks for the help. This happened after initial install of VS2008 Express.

Answer 18

 

I had the same issue, I tried the below command and it solved the issue.

 

devenv /ResetSkipPkgs

 

 

Answer 19

Hi, I'm really new to C# so I don't even know how what or how to access the VS 2008 command prompt.

Can you walk me through step by step as to how I can fix the error of the compiler?

Any help is appreciated.

Thanks.

 

I really need a step by step explanation. For example, where can I find the 5 registries and where is HKEY_CURRENT_USER?

Answer 23

 

Thanks a lot....

Answer 24

For those who don't know how to navigate to the system registry (I had to look it up), go to START>>>RUN, type in REGEDIT, hit enter, and the registry editor will open up, then just expand the folders until you find the values you want to change. Right click a value, choose modify, and your home free.

By the way, this regedit fix solved my C# problem also.

Answer 25

thanks a lot.. you saved my time when it was very hectic.

thanks again

Answer 28

Hi everybody!

I've the same problem and first of all I tried the way of registry editing but in HKCU/Software/Windows the folder VCSExpress in not present.
So I tried to find the Key in HKCU/Software/Windows/VisualStudio/9.0/Packages but there are no keys there!
Then I tried the command devenv /ResetSkipPkgs but I've the same error.

Any ideas?
Thanks!

Answer 29

Thanks so much.  I was having this problem and I thought it was because I had Express edition installed prior to installing the full version (VS2008).  It opened my project with no issues after changing the registry key.

For VS 2008 the path is

Answer 52

The solution "devenv /ResetSkipPkgs" didn't work in my case.

I know another way.

Install Silverlight tool for vs2008 sp1. Then the problem may not appear.

(Although not in the case of silverlight projects, all c# projects problems have solved.)

Answer 53

Hi,

Thank you so much. it did work for my problem as well.
Those who see that

devenv /ResetSkipPkgs

is not working, try this
first write:

devenv

then give space and after that write:

/ResetSkipPkgs

it will then work..

Thanks a lot once again.

Answer 54

"devenv /ResetSkipPkgs"

and

"devenv" then put space and type "/ResetSkipPkgs"

I couldn't understand difference of two things you(kmnsh)'ve mentioned above. uh-huh?

thanks op183 for the solution.

[HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\Packages]

Ok, you can open: run->cmd type command:

cd c:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE

and then type: devenv /ResetSkipPkgs

Ok, good job!

 

Answer 63

Thanks for the great suggestions. 

 

Changing

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0

to

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\ABC 9.0

solved all my issues. 

 

Next time I opened VS2008 the \9.0 folder in my registry was totally recreated and actually VS2008 seems to be opening a lot faster!!!!
