Hi, Sorry but if you didn’t take a backup before OS re-installation, no chance to have it working… Did you erase the hard drive during re-instllation ? ---

Hi Arshadez, If you didn’t take a backup of the dolibarr database then its difficult to restore the system. You will have to recreate it with printed documents. Sorry! :unhappy: ---

The folder that contained the Doliwamp installation should still exist unless you formatted the hard drive. The shortcuts to it will have been removed by the re-install. Find the installation and copy it somewhere safe for your reference while you get it working. If you cannot find it, install Doliwamp on another computer to see “where” it gets installed by default and use that as your reference to find and fix your old install. ---

Hi, The documents are still there you have normally a document directory in the doliwamp directory could you check ? FOr the database this is tricky, you should try something like that : [https://stackoverflow.com/questions/35388719/recovering-mysql-database-after-uninstalling-wamp](https://stackoverflow.com/questions/35388719/recovering-mysql-database-after-uninstalling-wamp)
