ERROR: The cabinet file 'Sql.cab' required for this installation is corrupt and cannot be used

Question

As the title indicates, I'm having this error during installation. It occurs when I try to install
the "Management Studio" part of the program. I've tried a bunch of things like
copying to hard drive and installing, but to no avail. To isolate the problem, i've even tried removing Reporting services, since at the time of failure it seems to be trying to install/configure the Microsoft.Reporting Services dll.
Additionally, I have SQL Express installed (installed it separately, not as part of the SQL 2005 DVD), VS 2005, .NET Framework 2.0, SQL Management Studio Express CTP. Could the Management Studio Express be causing a problem?
Please note:
Although the error is about missing / corrupt Sql.cab, I have searched the entire dvd for the said file, but there is no file called Sql.cab on the dvd. Am I missing something?
Any solution would be greatly appreciated.
TIA

I was installing SQLServer2014_Developer which I had just purchased as a 64bit iso download to VirtualBox Windows_10_64bit Instance that i had just created.
I got the following error about 90% through the SQLServer2014_Developer install:

Reading though the many Google hits going way back AD-2000/AD-2006/AD-2011/AD-2014 for various installs including SQLserver_2008/2012 etc
I noted that in the main there were x2 common themes.
1. Problem with corruption the original download.
--- Although I had not run the download checksum
--- I had previously just installed SQLServer2014_Developer successfully, so at the minute, I was confident downloads were ok.
--- Many hits mentioned this 'Sql.cab' file and 90% of the install had been successfull -
--- I figured the chances of us all having corruption of this one files were agaianst the odds and
---   probably re-downloading it would not fix this - but I kicked a re-download off anyhow .
While it was running ...
2. Network issue when installing - some of the hits asked if could be related to Virtual drives.
--- This struck a chord
--- I had downloaded the SQLServer2014 .iso to my host PC and then copied it onto one OneDrive so I could access it within the VirtualBox_Windows_10.
--- From within the VirtualBox_Windows_10 I had then used SetupVirtualCloneDrive5450.exe to mount the OneDrive SQLServer2014 .iso and then autorun the install.
What worked for me ...
--- I decided to
--- 1. Copy the same SQLServer2014 .iso that had failed to install x2 from OneDrive to the c:\ root of the VirtualBox_Windows_10.
--- 2. Remount the same SQLServer2014 .iso from c:\ again using SetupVirtualCloneDrive5450.exe.
--- 3. Re-run the SQLServer2014 install using the repair mode.
This time the [Maintenance] [Repair] install completed with all elements showing installed successfully.
Hope this helps
