swprv.dll register failed - solution!!

I found that I was not alone with the above problem when trying to

re-install the Volume Shadow Copy Service. There were many articles with

instruction on how to re-install / repair it, however they all said

essentially the same thing and I noticed that many people were having

trouble getting swprv.dll to register during the process.

Unfortunately, there was no working solution offered by anyone to this

problem, other than to re-install windows. I WILL NOW DESCRIBE THE SOLUTION

THAT WORKED FOR ME!!

(this solution was used in XP - not sure about other OS's)

1) Launch the Component Services window, which is under Administrative

tools.

2) Expand Component Services > Computers > My Computer > COM+ Applications

3) In there locate the item called "MS Software Shadow Copy Provider" and

right click it, choose 'Export'.

4) On the wizard that opens, click 'Next'.

5) type a location eg. c:\MS_shadow_temp and click 'Next'

6) Click 'Finish'

7) Right click the item called "MS Software Shadow Copy Provider" again but

this time choose 'delete'. If delete is not an option, then choose

'Properties', go to the advanced tab and remove the tick from the box with

says 'Disable deletion'. Then you can delete it after you have pressed 'OK'.

8) Delete the following key from the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SwPrv

9) Rebuilt the COM+ catalogue usin the instruction available commonly

online.

10) Restart

11) Launch the Component Services window, which is under Administrative

tools.

12) Expand Component Services > Computers > My Computer > COM+ Applications

13) Right click on 'COM+ Applications' and click 'new' > then 'Application'.

14) Click Next on the window that opens, then 'Install pre-built

application'. Click next.

15) Browse for the file eg. c:\MS_shadow_temp.msi

16) Complete the wizard (I can't follow beyond this point or I might mess up

my system again).

17) Restart your machine.

18) run " regsvr32 /i swprv.dll " at the cmd prompt after changing to the

windows/system32 directory (otherwise apparently it fails).

19) Restart and you should find it all working. If not, try installing the

COM+ catalogue and restarting again.

Another problem that I had and I noticed others had too, but didn't see a

solution for is error 5013 as shown below:

I fixed this error on my XP SP2 machine by installing the Indexing Service,

which I removed many months ago. Perhaps it was doing that that messed up my

VSS? Anyway, fixing this was the final part of my problem. Once I had

re-installed and enabled / started the indexing service in 'Services', my

shadows copies were working again!

Yippeee!!!!

Hope this fixes it for you :)

(would love to know if it does after I just spend an hour writing it up :)
