Installation issues

I just bought Smart SEO for nopCommerce version 3.8. I have copied the SevenSpikes.Core and the SevenSpikes.Nop.Plugins.SmartSEO folders into the Plugins folder and restarted application. When I go to install through admin CP I get this error...

Short message  
Access to the path 'h:\root\home\********\www\site1\App_Data\InstalledPlugins.txt' is denied.

What needs to be done?

Greetings,

Thank you for reaching out to us!

Are you able to install any other third-party plugins?

Please make sure you have write permissions to the folders listed in the nopCommerce install documentation.

I have installed plugins before. File permissions are read/write/execute.

I believe it might be an issue with the shadow copies. The application uses shadow copies of all the plugin DLL files in the ~/Plugins/bin directory in order for functionalities like Upload plugins and themes from the administration to work.

However, there is an issue when the application pool the store is running on has an overlapped recycling turned on. NopCommerce deletes these shadow copies every time the store restarts so it can create a new one. However, during the overlapped recycling the old process running the application pool and the new one that needs to replace it (during recycle) overlap (hence the name), and the old process still holds the shadow copies when the new one tries to delete them resulting in this concurrency.

The only known solution to this issue is to disable the Overlapped Recycle of the application pool running your store. This can be done from the advanced settings of your app pool.

Please try disabling the overlapped recycle in your IIS.

Dear Customer,

Sorry, it is not allowed to disable IIS overlapped recycle on the shared server.

Thank you.

Bump bumpity bump bump...

What kind of service is this?

Greetings,

Thank you for your reply!

It is a known issue in nopCommerce and this is the only solution we are aware of and if you disable our products, your access to another plugin in the list of plugins will be denied. Please read more about it here.

Please consider switching to a VPS server where you will have full control over your server or switching to a hosting company that allows this configuration in a shared environment.
