My TIA Portal (V12 and V13) crashes every time I select a tagname field in a ladder network and start typing. Everything else seems to work fine in the program. But the second I send the first letter from my keyboard to the tagname field, the portal crashes. It almost looks like there is something wrong with the function that searches for matching symbols based on the keyboard input.

I have submitted a support request earlier today, but I am just curious if anyone here has had the same problem. If so, can you please tell me what's going on??

Edit: Caused by AVG antivirus program. Solution: disable AVG protection or add TIA Portal exception. Switching antivirus program may also work.

hi Nullspace,

something got wrong with your TIA-Portal-installation.

the first what you should do, and I think the Siemens-Support says the same, is to do a repair installation of your TIA Portal. Do this with Admin-rights(right-click on setup.exe -> run as admin) and with deactivated anti-virus-scan. 

If you don´t have the latest updates of TIA(V12 SP1,Upd5/V13 SP1,Upd4), install the updates in the same way.

hope this helps,

regards,
