Installation problem

Hi,
Congratulations for this great component that I'll buy since my site will be validated by my client.

But now, I'm driving crazy with the installation on my ISP site...
I've installed your component on a few local sites without any problem.
Now I'm getting the following errors :

JFolder: :files: Path is not a folder. Path: /var/www/---/httpdocs/tmp/install_4ecc2493aafdb
JFolder: :folder: Path is not a folder. Path: /var/www/---/httpdocs/tmp/install_4ecc2493aafdb
JFolder: :files: Path is not a folder. Path: /var/www/---/httpdocs/tmp/install_4ecc2493aafdb
JInstaller: :Install: Cannot find Joomla XML setup file

I made a chmod -R 777 httpdocs on the whole site and Hikashop doesn't install !
BUT others component like Akeeba DO !!!

Because all directories are writable, could you put me on the way to understand the problem ?
Thanks by advance.
Regards

Joomla 1.7.2 with Directory Permissions Writables especially /tmp

Strange to do it that way ???
for information, the hikashop.zip was copied in /tmp
I just :
- unzipped it under Unix
- then tried Joomla Install from Directory -> same error.
I had to :
- chmod files and directories to 666 and 777 for having installation working
- clean /tmp directory
- do again chmod

It's quite a constrainst for an install and updates for your great component

May I remind you that Joomla updates and other components are installing well in my environment.
Could it be something specific in your installer ?

Thanks for help
Regards

If this can help for improvements, I've got the same installation problem with JCE and last Joomla 1.7 updates.

With regular installation, it hangs with .zip packages, but worked with .tar.gz packages
It's like if the Joomla unzip is having a writing problem.

Maybe you could provide a .tar.gz package of Hikashop ?

Regards

I had the same problem. On one server the components installed without issues form the zip package, on another server it wouldn't install with the mentioned error meessages.
I repacked the intall package into .tar and it worked.
Thought I'd post it here, so others having this problem find a solution.

If this can help too, I made the manip to upgrade to 1.5.5 version.
I repacked the .zip in .tar, with 7zip and it worked like a charm !
It's simpler than FTP solution.

Strange problem ! Obviously not a permission problem on servers.
Regards
