Sorry for not replying to this earlier as I was just reporting as requested but I have run across something similar today while running deconvolution.
Error Message reads as follows: Pixinsight Error PCL Win 32 System Exception.
Address: 00007FF9DBDF1F08 with exception code C0000005; Access Violation; Invalid Memory Read operation at address 0000000000000018
Requested I save my project and close program, which I did.
This is a first time occurrence, the previous report has only occurred that one time.
Currently running Windows 10 but did not have the latest updates for PI installed at the time (3of them).
I was able to save all my work without an issue.
I had run Deconvolution several times with changing parameters without issue on a preview and was executing on the entire image when this occurred at the
conclusion of the iterations. I missed the first message but it did pertain to the swap files but I did not note the particulars at that time.
I restarted PI and just opened my image and ran Decon once again with the exact same settings without and issue.
Just the usual gremlins in Windows as far as I'm concerned
I would classify this as another sporadic issue but just in case
Love this program!
