A typical compatibility error - the program does not support the older version of the DET file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular DET file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Sage
When reading, a message appears that the file was encrypted or corrupted. The encrypted file DET except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. Copying the DET file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the DET file again. However, some background programs may block the DET file while scanning. If nothing helps, please reset the device.
