Hi Madam,
we are using Test Complete 11.2 in our system and we still facing this TCHookX64.exe issue in one of our MCAfee installed 64bit system. We observe this issue after upgrading system from Test Complete 10.3 to 11.2. With Test Complete 10.3 this issue was not observed and its observed only in 11.2 and its not produce often. Every time we are reinstalling 11.2 so first 2 or 3 times this issue wont come but later same problem.
Please find the attach screenshot for the same. can you specify any workaround method to avoid this error in future ?
