Just a guess, but look for a file called ToadActions.dat. It will be in your user files folder. Rename it and then try to start Toad again. ---

Hi Sir, in the reply for the initial thread it was mentioned to use higher version of software whereas I am using higher version as mentioned in that reply. I.e. My version “Support Bundle for Toad for Oracle 12.7.1.11” 64 bit. Please provide suitable solution.

I think you might be getting your threads crossed. The initial reply in this thread was to try renaming ToadActions.dat. to see if that is the cause of the error. ---

I did try the renaming of the ToadAction.dat file, and it recreated the ToadAction.dat file after restarting Toad, but it did not resolve the issue. After posting above, I tried deleting the whole folder under AppData. Then I reopened Toad and it worked. Sorry for the slow response. ---

No problem on the response time. If you still have that folder, look for Toad.el or Toad.elf inside it… Send me the file and I may be able to isolate the problem. You can send it to [john.dorlon@quest.com](mailto:john.dorlon@quest.com) Thanks. ---

Can you send/attach the entire call stack? The first few lines don’t help too much. ---

Hi. I am having a similar error (Stream Read error) with Toad 11.5 when I open a session browser. I tried renaming the files mentioned in this thread and another thread with no success. Can you please help? ---

Hello, I experienced the same “Stream read error” and tried renaming the files above but it didn’t remediate the problem. The other suggestion was to purge the entire contents of the C:\Users\\AppData\Roaming\Quest Software\Toad for Oracle\11.6\ folder. I backed it up first and then deleted it. Restarted Toad. I logged into one of my databases and was then able to open a Schema Browser window without receiving the error.
