This answer helped me too. 

I originally installed Tia Portal  from an iso that wasn't mounted when trying to install the HSP and got an error. 

Hello guys! I hope you find this information usefull.

I had the same problem, and I launch the Tia Portal with administrator rights, and It worked!

Best regards,

Tx to you, it's working

I know, very long time from question about problems with HSP update of origin person "DennisA".

By me was same problem in all TIA versions.

Qiude for all: Solution is start TIA Portal like Administrator (because corporate privilegs blockate standart user level privilegs in installation of any applicatons on PC). Than all updates full function. Few updates disfunction for missing need sub software (example additional safety software for safety units, etc.)

Have a nice days all.

Thank you very much! This answer helped me a lot.
