I solved the problem as follows. I installed ISTA on the second Laptop where the installation went without any problems. I imported the full 4.41.50 data. I copied everything from the laptop, it was about 400GB. I can't remember the number now. I copied everything to an external drive. and then I copied it to the laptop where the installation did not work. I edited the register where the ISTA version is 4.39.20 + 4.41.50 data full. Everything works on the laptop. If you have such a problem, try another laptop. Alternatively, if someone has solved this problem differently. Write. During my time working with ISTA, I have not encountered this error. I don't understand it, I read everywhere that a colleague wrote that the file is damaged. only it could be damaged when it works on the other laptop. Thanks to everyone who gave me any advice. Hi.
