Alachisoft NCache 4.1 - Online Documentation

Evaluation Period Expiration & Extension

By default, when you install NCache, it is installed as "Evaluation Copy" and remains valid for 60 days. After this period, NCache will stop working.
Indications of NCache Being Expired
You will be able to notice that NCache evaluation period has been expired from the following places:
• NCache API will no longer work. You won't be able to add or fetch items from the cache.
• NCache Manager splash screen will show NCache evaluation period has expired.
• NCache Manager window title will show "Expired"
• NCache Manager HELP -> ABOUT dialog will show NCache as being expired
• You won't be able to add an expired cache server to a cache cluster from NCache Manager
• You won't be able to start cache on an expired cache server
Extending Evaluation Period
If any of the above happens, then its time to either purchase NCache licenses or if you need an extension to your evaluation period, you can obtain an "Extension Key" from Alachisoft Sales. Please send an email to (or to your account manager if you're already in touch with him/her) and ask for an extension key. You will be provided a 30-day extension key.
Once you have obtained extension key, please run "Run Activate NCache License" program from "%Install Directory%/NCache/bin/NActivate" path. Below is a screen shot of the screen which will be displayed. Please select "Extend evaluation period" option and then click Next button .
Once you click Next button, you will see the screen shown below. Please enter the extension key provided to you by Alachisoft Sales and then press Finish button. If this key is valid, you will be prompted with a Success message. If the key is not valid, you will be prompted accordingly.
Please note that a 30-day extension is valid from the original installation date, not from the day you are trying to extend. So, if you waited for 15 extra days after the initial 60 day evaluation period to extend it, you'll only get 15 extra days extension.
