Blackboard Collaborate, Java Runtime Environment, and Windows 8/8.1

Strangely enough, Java Runtime Environment (JRE) fails to register javaws.exe as the handler for .jnlp files when installed in Windows 8/8.1.

Just remember to choose javaws.exe, not java.exe nor javaw.exe.

Further more, Blackboard Collaborate insists on using 64-bit JRE on 64-bit Windows, i.e. visit the directories and files usually found in C:\Program Files\Java, not the ones found in C:\Program Files (x86)\Java.

BTW, download your clean JRE from or from On 64-bit Windows it’s usually wise to download and install both 32-bit and 64-bit JRE, i.e. Windows x86 Offline (e.g. jre-8u20-windows-i586.exe) and Windows x64 (e.g. jre-8u20-windows-x64.exe).

Manually rebuild Performance Counters

I tried to install some construction estimation software requiring MS SQL Server 2008 on a computer running Windows 8 only to encounter an unusual anomaly. MS SQL Server 2008 refused to install due to corrupted performance counters. The error message was kind enough to mention, but you should really go and visit Continue reading Manually rebuild Performance Counters

Adobe Flash Player, MS Windows 8/8.1, and MS IE 10/11

Yeah sure enough, Windows 8/8.1 and IE 10/11 has its own builtin Flash player. This highly potent combination outright refuses you to download the real Adobe Flash Player from Adobe’s website. It hasn’t occured at all to Microsoft that we, the users, might need the real Adobe Flash Player for software other than IE, say Adobe Acrobat Pro. Way to go Micro$oft!

Toshiba Satellite laptop, Windows 8, and Secure Boot – what a combination!

A student’s Toshiba Satellite laptop equipped with Windows 8 and Secure Boot refused to shut down by simply pressing the power button. The solution is to hold down the Fn button prior to holding down the power button. Keep both buttons depressed until you hear the laptop actually shutting down. Boy, do I love Secure Boot?

Relocating the Client-side Caching database in Windows 7 and 8

Sometimes the default location of the Client-side Caching database is just plain unsuitable. Client-side Caching, or CSC, is used for storing offline files, local copies of files normally stored on Windows shares, stored on Windows servers. (The Norwegian term is «frakoblede filer».)

The default location for the CSC database is C:\Windows\CSC. If you like to keep the OS and the software separate from any user data, or want to store the CSC database on a dedicated local partition, then it might be useful to change the location to, e.g. D:\CSC.
