I have tried downloading and installing reshacker but have had no luck. How do I manually install reshacker? Is their a way to get past installing reshacker?
You do not have to install any software by yourself to use WinReducer Software, there is an integrated and automatic download of all third party software !
This is done by WinReducer itself ... have you read this official tutorial which describe the automatic configuration :
Basically, the 1st time you run WinReducer the "OPTIONS - Configuration" page will be opened to help you install all third party software (like reshacker) ... Just click one by one on each software name (7zip, ImageX, ...) and WinReducer will automatically download the executable files, then extract all necessary files. So, you do not have to install something !
A new build will come soon and it will be much more simpler and easier to understand ...
Have a good day !
