The unattend answer file contains an invalid product key. Either remove the invalid key or provide a valid product key in the unattend answer file to proceed with windows installation

If ever you have tried using VMWare Workstation to install Windows OS, as soon as you select the .iso image, it will prompt you for the product key and you would have entered the same. But once the installation starts, it will give you this message.

The unattend answer file contains an invalid product key. Either remove the invalid key or provide a valid product key in the unattend answer file to proceed with windows installation

All you need to do is, Power Off the VM. Open the autoinst.flp file, find where the product key is and re-type it... guess this is a bug with VMWare which adds some special characters to the product key when given initially.

Once you have saved back the file, you can re-start the installation and it will go through successfully.

    After wasting an hour trying other things I found an alternative solution was to not enter the product key when creating the vm. VMware issued a message stating I would have to enter it later, but that's fine. At least it got it running the setup proper.

    Your the best.
    It works great just open the file whit notepad, and delete serial number, and then write it again and save the file.
    Keep up the good work.

    Or you can leave it blank and proceed the installation without product key. Then on a later date you will be propted to enter the key

Using External Content Types with Stored Procedures with Input Parameters

Image
You must have tried External Content Types - the exciting new feature in SharePoint 2010 to connect to an external SQL table and provide a list where it lists, creates, updates data straight into the SQL table. People always wonder, how do you get a ECT to work with a Stored Procedure, one that has input parameters. You could do it this way... Step 1: In your SharePoint Designer 2010, create a new external content type Step 2: Connect to your SQL Server and then make sure you see the Routines (your stored procedures must be listed here) Step 3: Rt Click on the Stored Procedure name and create operations for "Read Item" and "Read List" - both are required for the External Content Type's SharePoint list to be created. During both these wizards, in the Input Parameters, your SP's Input Parameter will be listed. Here, you need to create a filter, which sends out it's value to the SP's filter. For example, if your SP's Input Parameter is @Emp...

Validate a SharePoint Date Field against Current Date in Javascript

Consider the following scenario: You have a SharePoint Site which has its regional settings set to English (UK) - so that the date format becomes dd/mm/yyyy in all date pickers You would like to validate a particular date field in your List or Document Library against the current date If the validation does not pass, you should not allow the form to save So what the script does is: Uses the sputility (check my previous posts and also look at http://sputility.codeplex.com) to get the particular SharePoint date field It comes out as a date datatype, so I cast it to string Since the format is in dd/mm/yyyy and Javascript compare and date functions work only with mm/dd/yyyy, I am converting them back to that format then using UTC string conversions and comparing... Enjoy! <script type="text/javascript"> function PreSaveAction() {  var createdate = SPUtility.GetSPField('Date of Creation').GetValue();  var createdatestr=createdate.toString();      ...
