Hi, I’m an experienced troubleshooting professional offering you with the one-stop solution to various problems. In case of QuickBooks Error 3371, it would like to first identify the exact reason why it is happening. Missing or damaged file might be the main reasons behind the arrival of the QuickBooks error code 3371. Once I identity the causes, I will definitely leverage the QuickBooks Install Diagnostic tool. Hereafter, I also want to update QuickBooks to replace the older version and make sure it is not happening further.
