I made a copy of my Quicken data file and named it TEST. I ran File > File Operations > Validate & Repair > Validate. The program began running then stopped on "Validating file… Checking stock splits." (See attached image.) After an hour, I broke the connection and again logged into TEST.
I ran a transaction report of my investment accounts and found nine stock splits. I deleted each entry and then saved the file as TEST2. I ran the Validate program on TEST2 with the same results – stuck on "Validating file… Checking stock splits." (Even though there were no Stock Split transactions.) After an hour, I force closed the file.
I am running Quicken Release R 26.23 (the latest) on my Windows desktop. Although this issue has been mentioned, I have not been able to find a resolution.
