I have an odd problem running spire.pdf on asp.net web application. I have read the forums and apparently the spire.pdf is PartiallyTrustedCallers ready. However, I have just download the free version of the product and I am impressed how quickly it generates a single page PDF from a HTML string.
The site is hosted with fasthosts and while they are the biggest in the UK they are also the most restrictive in app development. The app was developed using VS2008 and .Net3.5. There are no intentions to upgrade to .Net4 but the site has been compiled in VS2013 for testing purposes.
The web runs and creates the pdf in the dev environment but when I upload it to the hosted if get a Required Permissions Cannot Be Acquired error. I don't know if this is because of the hosting company or the DLL itself but when I remove the DLL from the bin directory the site starts to work. The error returned is below and shows that the DLL that is trying to acquire the security policy is the spire.pdf. I have also logged this with fasthosts.
thanks for your help.
