The registry database is not set up correctly for the SIMATIC Manager.

Install STEP 7 again. HELP ON MESSAGE 3280:503

Description of Error: Entries necessary to start the SIMATIC Manager cannot be found in the registry. Parts of the keys ‘s7tgtopx’ or ‘s7tgtopb’ are missing.

Registry entry 'Software\Siemens\STEP7\2.0\Applications\s7tgtopx' not found or incorrect.

 Running installed Step7 V5.6 with Administrator Rights solved this start problem.

В случае появления подобной ошибки при запуске Степ7 - запустите его по меню правой кнопки от Имени Администратора.

Split from current trial software for STEP 7 V5.6.

I had the same problem, running Step7 V5.6 on Windows 10 64-bit. My installation used to work, but suddently it stopped, with the same error. I have tried to reinstall/repair the installation as the error message suggests, but without any luck. I also tried to start the installation as an administrator - but still with the same error when trying to start Simatic Manager.

I then tried to start Simatic Manager as Administrator - and yes, now it starts without any issues.

How do you fix the same issue with version control software eg. VersionDog?

I am able to start Step7 from the exe. using "run as administrator" but not with VersionDog.

thank you very much.

Thank you also for this "solution".

Is Siemens working on a fix for this problem?

I have also been struggeling with this problem and because of our IT policys I am not able to start Step 7 as an administrator so the only option for me was to find a solution so I could continue to use Step 7 without a administrator account

I have done what every one else has done before me and first repaired the istallation and after that uninstalled and reinstalled Step 7 without any luck.
So I asked a colleague to log in to my PC with his account (also not admin) and he was able to start Step 7!
But when I switched back to my account I was still not able to start it...

I ended up deleating my windows 10 user account on my computer and then creating it again and now it works!
So in my case something in Step7 related to my windows user account on my computer had crashed and when I created a new account againg it "fixed" Step 7.

I had a similar problem on Windows 10 recently, but there were nothing about 's7tgtopb'. Just this:

Registry entry 'Software\Siemens\STEP7\2.0\Applications\s7tgtopx' not found or incorrect

Repair the Step7 installation did nothing.

Then I uninstalled mere Step7 v5.6. Open Windows Registry and via Search deleted all the 's7tgtopx' Keys that I was allowed to delete and that where not from the TIA Portal level. Then installed Step7 v5.6 again and it started successfully.

I want also add that this error comes after my own experiments with that very registry key. I was exporting and importing some values for the sake of getting a .reg file with my favourite Step7 configuration (filters, columns, data, projects path, warnings). And I guess I succeeded.

i have also the same issue.
OS: Windows 10 x64bit

it's working when i tried to run it as administrator.

but's not the proper solution.
needs to fix this issue.

 check if the Registry keys exists

HKEY_USERS\>UserSID_Classes\VirtualStore
HKEY_CURRENT_USER\Software\Classes\VirtualStore

if yes then delete the keys and the SW should be run without the "Run as Administrator"

Regards

I works! I confirm. Deleting the registry key HKEY_CURRENT_USER\Software\Classes\VirtualStore solved this issue. The other key doesn't exit in my case.

Thanks a lot!
