Hi,

Do you have any other PHP software installed in your system?

Yes I have. I have installed PHP Manager for IIS7 and PHP 5.2.14 via Microsoft Web Platform Installer 3.
Thanks / Tomas

I have now unistalled every other instance of PHP, and still the same problem occur.
Thanks / Tomas

Hi,

It could be that Microsoft Web Platform Installer installs files on your system which could produce this error. We will investigate on our side.

OK – I managed to solv this problem, the way you suggested above, beltran. I noticed that I had yet another instance of PHP. After deleting this the install of bitnami work OK.
Thanks / Tomas

Hi,

Could you tell us which PHP instance was the problematic one? Have you installed another Microsoft Web Platform instance installed or it is a different one?

I have Web Platform Installer 3.0 and PHP 5.2.14 and PHP 5.3.3 both for WebMatrix

Thanks for the info.
