NCache 4.6 - Online Documentation

Evaluation Period Expiration & Extension

By default, when you install NCache, it is installed as an Evaluation Copy and is valid for 60 days only. At the end of this period, NCache will stop working.
Indications of NCache Being Expired
You will be able to notice that NCache evaluation period has expired from the following indications:
1.     NCache API no longer works. You are not able to add items to the cache or fetch them.
2.     NCache Manager splash screen shows "NCache evaluation period expired" message.
3.     NCache Manager window title shows “Expired”.
4.     In NCache Manager, the About dialog (accessed from Help menu) shows NCache expired.
5.     You are not able to add an expired cache server to a cache cluster from NCache Manager.
6.     You are not able to start cache on an expired cache server.
Extending Evaluation Period
If any of the above happens, then it is time for you to either purchase NCache licenses or if you need an extension to your evaluation period, you can get an Extension Key from Alachisoft Sales. Please send an email to (or to your account manager if you are already in touch with him/her) and ask for an extension key. You will be provided a 30-day extension key.
You can extend your trial version only 4 times: after that you have to purchase NCache licenses in order to use NCache.
Once you have obtained the extension key, please follow the steps given below to extend your evaluation period.
  • Run NActivateWizard from "%Install Directory%/NCache/bin/NActivate" path.
  • Select Extend evaluation period option on the following screen and click Next.
  • A new dialog box will appear. Here, enter the extension key provided to you by Alachisoft Sales and then click Finish.
  • If this key is valid, you will be prompted with a Success message. If the key is not valid, you will be prompted accordingly.
A 30-day extension is valid from the original installation date and not from the day you are trying to extend. So, if you have been waiting for 15 extra days after the initial 60 day evaluation period to extend it, you will only get 15 extra days extension.
