Problem with MySQL when installing Drupal

When installing Bitnami Drupal 6.15 for Windows, MySQL reports the following:
ERROR 2003 (HY000)cannot connect to MySQL server on ‘localhost’ (10061). It also mentions the password.

I read somewhere that there might be a conflict with a previous install of MySQL and that another password is set. To remove MySQL I uninstalled Bitnami Drupal and deleted the Bitnami directory with the MySQL database. I also searched my harddisk for any MySQL entries but found nothing.

When reinstalling Bitnami Drupal I get the same problem. Is there another (hidden) MySQL database which is conflicting? Any suggestions in resolving this?

Do you have any firewall enabled? Could you disabled? Does your password have withe spaces or strange characters? Could you post the MySQL log file (/mysql/data/mysqld.log)?

Thanx for your reply.

I switched off the firewall and started the stack: no connection (“The site is currently not available due to technical problems. Please try again later. Thank you for your understanding.”)

My password: only has letters and numbers

The log-file /mysql/data/mysqld.log does not exist. However, I did find the error-file MobileStudio.err in that same directory. MobileStudio is the name of my laptop. It’s also a log file and mentions an error with INodb. I’ve attached the file. Could it be that AVG antivirus is blocking or checking the database while installing MySQL?

Attached Files

Yes,

It seems that your antivirus is checking the database files so the MySQL server can not use them at the same time:

100125 21:33:12  InnoDB: Operating system error number 32 in a file operation.

InnoDB: The error means that another program is using InnoDB's files.

InnoDB: This might be a backup or antivirus software or another instance

InnoDB: of MySQL. Please close it to get rid of this error.

I tried the following:
- uninstalled AVG antivirus, unistalled drupal, removed drupal directory, rebooted, re-installed drupal: same problem
- uninstalled Tuneup Utillities, unistalled drupal, removed drupal directory, rebooted, re-installed drupal: same problem
- unistalled drupal, removed drupal directory, rebooted, re-installed drupal and used a new identity and password with only lowercase letters: same problem

I’m a bit at loss and installed Bitnami drupal on my netbook, which works fine technically

It is difficult to know what process is using the MySQL database files. Process explorer could help you.
