In rare cases, it is possible that when uninstalling Dewesoft not all the files were removed. This might cause an issue when installing the Dewesoft back to the computer.
To resolve this issue you will have to go to Windows registry and delete some of the keys manually. Depending on a version of Dewesoft that you are trying to install you will need to use a different search keyword.
These registry keys listed below are for the new DewesoftX® 2020 version.
Here you can find the list of available Dewesoft versions:
