Following are the recommendations in envelope settings that needs to be followed while protecting a web application dll:

1) ‘Message output mode’ should be ‘eventlog’ or ‘standard error log’

2) Copy the supporting files in System32 or any other %PATH directory:

• hasp_rt.exe
• hasp_windows_xxxxx.dll
• hasp_windows_x64_xxxxx.dll
• haspdnert.dll
• haspdnert_x64.dll

 3) Use different feature id for global and feature level
