If you are having a problem every time you run an install then I would suspect that there is something wrong with your sever setup and/or specification.

Out of interest, and following on, can you try upgrading the 3.1 install to 3.2 to see what happens following this:
Your server must be running at least PHP 5.4 or higher.
phpBB 3.2 is mostly compatible with 3.1 and most of the previous files will need to be removed prior to upgrading.
To upgrade, perform the following steps:
Make a back-up of the original files and database
Deactivate all styles except for prosilver
Deactivate any extensions which are not compatible with phpBB 3.2. Check with the extension author to find out if an extension is compatible or not.
Ensure that the activated spambot countermeasure is one of the standard phpBB plugins (Simple image, GD image, GD 3D image, Q&A, reCaptacha).
Set British English as the only language pack and delete all other language pack directories from your server
Delete all of your phpBB 3.1.x files EXCEPT for the following:
The config.php file
The /ext/ directory
The /images/ directory
The /files/ directory
The /store/ directory
Upload the contents of the phpBB3 directory from the uncompressed 3.2.x Full Package (EXCEPT for config.php) into your forum's directory (Note: you don't want to overwrite your original config.php file)
Browse to www.example.com/install/
Click the Update tab
Click the Update button
Select "Update database only" and click Submit
Wait for the progress bar to reach 100% and for a message indicating that the update has completed
Delete or rename the /install/ directory
