Hello Laur,
Thanks for writing us back.
We found that there were some reported issues with the LDK RTE 7.6 over certain updates on windows 7. However, those were fixed in the later releases. Hence, please be suggested to try the latest RTE version 7.8 and observe the behavior upon the installation.
