I’m using Xampp to run Dolibarr, could not install with Doliwamp, and now getting this error in the final step:

So I tried to install it again, without removing anything:

I don’t know which directory to go to log into Dolibarr.

Google search Said to enable Dolibarr module, but no such module is present in Xampp control panel, Or do I have to go to PHPmyadmin to open dolibarr.

I have some programming knowledge, but I have never used a server application like Dolibarr. Please dumb down your answers for me.

And thanks a lot for helping me out.

Hi @Unfinisher v. 21.0.0 is still in alpha which means not production ready yet.

You should download v. 20.0.0 from [Dolibarr ERP - CRM - Browse Files at SourceForge.net](https://sourceforge.net/projects/dolibarr/files/)

If you would like to help in Dolibarr development you can report the bug in Github

Thanks. I installed v20 and it worked. By the way, I noticed that step 2 only accepts root as the username, the superuser username also has the same issue. I had to redo this step a couple of times before it worked. I guess there is a bug in the installer.

Well anyway, I am very interested in further developing Dolibarr. I know Python and some basic web page programming. Can you suggest some good resources for learning PHP and Dolibarr dependencies?
