Missing option package message

Hello everyone!
System data:
KUKA KR5 ARC KRC4 robot
KSS 8.3.29

I am installing an ArcTech Basic 1.5 package on a KSS 8.3 system
I installed the KOP in the WoV, after that i tried to upload the project but i received message that the Option package needs to be installed on the controller.
So i installed it through the add new technology procedure on the controller and i can see the ArcTech buttons available also the technology package is visible in the installed options.
So i did the setup for the Fronius connection (Ethercat) and the ArcTech Basic setup - IO etc.
When i try to upload the project - it is going through until it start the installation of the project on the controller. After that it gives me error - The required option ArcTechBasic V1.5.7.2836 is missing on the controller! - i am attaching a photo of it.
I cannot attach the project as it is too big, but if needed i can upload somewhere an provide the download link
I tried also to copy the project on the robot and to activate it from there, but the result is the same - it says that the option package is missing on the controller.
Any idea what might be wrong?

Thank you in advance!

Hello again from me

i had a tough day - i tried to reinstall the Arctech package and it totally killed the KSS
Not sure what was wrong, but after i recovered the robot from an previous HDD image - i reinstalled correctly and now i am able to see the power source and to send signals.

The only problem i have now is the HOT/COLD welding button - it wont allow me to switch to HOT weld.
When i press it the message is: ATbg_HotRequest still TRUE
Also the buttons for Wire forward and backward are not working - I am talking about the status buttons
I can control wire forward and backwards through the outputs, but it seems the status keys are not defined properly.
Any idea where to look to define them>?
Thanks!
V

Any advise where should i look to check if the Arctech status buttons are connected to the right variable?

ok, just to update the thread as i solved the problem - it seems there was some old piece of software that was messing up the signals or the interrupts.
Anyway, i used a clean image of the KSS, reinstalled Usertech and Arctech and it is working fine now
