Installing .Net 3.5 using the Control Panel in Windows 10 (anniversary update) can sometimes be very slow. Alternative option is to install from DVD/ISO, like: c:\>DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:E:\sources\sxs Where: E: is the drive letter of DVD/ISO Reference: https://technet.microsoft.com/en-us/library/dn482069.aspx

I was able to install BlackBerry Playbook Simulator 2.1 on Ubuntu 16.04 64-bit by installing supported libraries, see here . Running the IDE ( /opt/bbndk-2.1.0/bbndk.sh ) fails with a message as shown below. /opt/bbndk-2.1.0/host/linux/x86/usr/bin/../..//usr/qde/eclipse/qde: error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory The above message says we don't have libgtk-x11-2.0 libraries. Since the IDE was compiled as i386 we need to install the library like: sudo apt install libgtk2.0-0:i386 Running the IDE again yields the following error message: (qde:2418): Gtk-WARNING **: Unable to locate theme engine in module_path: "hcengine", # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0xf771179d, pid=2418, tid=4131637376 # # JRE version: 6.0_24-b07 # Java VM: Java HotSpot(TM) Client VM (19.1-b02 mixed mode, sharing linux-x86 ) # Problematic frame: # C

Tried to install BlackBerry Play Simulator 2.1 on Ubuntu 16.04 64-bit but it fails with error message below. sudo ./installer-bbndk-2.1.0-linux-1032-201209271809-201209280007.bin Preparing to install... Extracting the JRE from the installer archive... Unpacking the JRE... Extracting the installation resources from the installer archive... Configuring the installer for this system's environment...

To fix it, do: $ sudo dpkg --add-architecture i386 $ sudo apt install libc6:i386 $ sudo ./installer-bbndk-2.1.0-linux-1032-201209271809-201209280007.bin Installation should now complete but the IDE will not be working. Next post details how to fix it. Follow-up post is here .

It is good practice to get the latest updates before installing VMware Tools. Open terminal and run the following: $ sudo apt update $ sudo apt upgrade $ sudo reboot If the update needs to upgrade the kernel, it is a good idea to reboot the machine before installing the tools so that we are compiling against the correct kernel. From VMware Workstation menu, do VM | Install VMware Tools... . $ mount cdrom $ mkdir ~/tmp $ tar -xvzf /media/u1/VMware\ Tools/VMwareTools-9.9.5-3735633.tar.gz -C ~/tmp $ cd ~/tmp/vmware-tools-distrib/ $ sudo ./vmware-install.pl -d $ eject $ sudo reboot Where: u1 = is the username, replace it with your username VMwareTools-9.9.5-3735633.tar.gz = version of VMware Tools in the ISO, change it with what's in /media/<user>/VMware Tools/ .

Click on user icon, a popup dialog will show up and show the IP address.

This is probably my silly mistake but it took me a while to figure out why it is not updating - it was paused!!! Did I do it? Maybe... but could be Windows just deciding to pause it. Anyway, un-pause it like as shown below. Reference: http://www.tenforums.com/performance-maintenance/31047-task-manager-not-updating.html

Even when the floppy hardware is removed from the VM configuration of a Ubuntu guest under VMware Workstation 11, the icon for floppy disk drive still shows up in the Launcher . To fix this  you need to disable Legacy Diskette A in the virtual BIOS of the guest. An easy way to boot to the virtual BIOS is to shutdown the VM, then select VM | Power | Power On to Firmware . Then change Legacy Diskette A: to [Disabled], F10  to save and exit. This should reboot the machine.

169.254.x.x is a link-local IP address that gets assigned automatically when, generally, DHCP is not available. On Windows operating system, this is called APIPA (Automatic Private IP Addressing). RFC 3927 defines the 169.254.0.0/16 address block for use in the link-local assignments. Note that routers are not supposed to route traffic from this address block.

On Windows 10 Enterprise version 1511 build 10586.589 + VMware Workstation 11.1.4, powering up a BlackBerry PlayBook Simulator 2.1 shows blank/black screen. The simulator was created around September 2012, it may have worked back in the day but with latest versions of the host OS and VMware it is not working using default configuration. The link from here mentions about supported graphics card, thus say, should support OpenGL 2.0. I am using a machine that supports Open GL 4.1 and still not working. To have a partially working simulator, change QNX boot option to 2. You can play with the simulator but developing an application that needs EGL does not work.

Installing BlackBerry Tablet Simulator 2.1 on Windows 10 fails with the error message as shown below. --------------------------- LaunchAnywhere Error --------------------------- Windows error 2 occured while loading the Java VM --------------------------- OK --------------------------- To fix this install x86 version of JRE (tested with jre-8u102-windows-i586.exe). Running the installer again will still fail. Workaround is to pass command line argument to the installer, like: BlackBerryPlayBookSimulator-Installer-2.1.0-1032-Win-201209272349 LAX_VM "C:\Program Files (x86)\Java\jre1.8.0_102\bin\java.exe" -i GUI Run the above command on elevated prompt.
