Retrieving the COM class factory for component with CLSID 80070005 Access is denied - export-to-excel

I am working on the application, and emport the report to Excel sheet. When I do that on my project this is working fine.But, when I run this application on IIS 7( Windows 7 64-bit) it gives me below mentioned errors -
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied.
I have tried lot of solutions available online, but with no use. Please suggest me what could be the problem and also solution to this problem.

Well, I was facing the same problem, it could be either of the following reasons :
The DLL required for the Excel you are using is not present.
Different versions of Excel on different servers.
Permission Issues
Please let me know what issue might be in your case, may be I could help you.

I had the same issue here, and in my case the problem was a faulty installation of the SQL ADMd.Net components. Try and reinstall those.
There is a DLL, named Microsoft.AnalysisServices.AdmomdClient.dll, which could not be found in my case. This caused a stackoverflow exception in my case. The admin reinstalled those components, and the DLL got installed, too. Deploying reports is now possible :).
I figured this out by attaching one VS instance with debugging enabled to another VS instance, with which I tried to deploy reports.
Also, I had to enable debugging for .NET Code in the settings.
I set a breakpoint at the function
Mscorlib.dll!System.Runtime.TypeHandle.GetTypeByName
And that's where I noticed, that the same block functions were called over and over, trying to load the DLL, but not being able to find it. It is the nLoad function.
(https://referencesource.microsoft.com/#mscorlib/system/reflection/assembly.cs,460c8abec12d58cd).
This eventally caused the Exception, and the exception code 0xc00000fd, which is a Stackoverflow exception.
I can't post images here, but I hope it's still understandable.
Best regards,

Crystal Report Engine error

i am stuck with a problem regarding Crystal Report 13. I am working on Visual Studio 2013 developing Web Application.
Previously i've developed reports and those were working fine but after some time on web page crystal report viewer stop rendering. I tried to resolve the issue by suggestions on different forums where i need to add reference of Crystal Report 13 files in my Web.Config. After all changes the problem was not resolved. Than people suggested me to re-install redistribution package of crystal report 13, i've done the same thing now there is a new problem which is quite different. Whenever i am trying to open page it shows following error:
Server Error in '/Abcd' Application.
The document has not been opened.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Runtime.InteropServices.COMException: The document has not been opened.
I've tried many forums and different suggestions but all seems useless, i've check the appropriate rights even try after giving full rights but still at same position.
I've found the alternative solution, before i was using 13.0.21 redistribution package which was using registry dlls version 13.0.2000.0, i was facing two problems using that particular version.
1. Unable to edit rpt file, whenever i tried to open it an error appear on screen that The operations is failed or unable to complete operation (something like that i don't know exactly what the error is but the summary is this)
2. When i try to open Crystal report viewer during execution, i've come up with error which i posted earlier.
What i have done for the resolution, that i've download Crystal report developer version 13.0.21 and install it with "Run as Administrator" because i creates some entries in your registry of windows, keep in your mind to close VS during installation. After successful installation both problems are solved but u need to change the dlls version in your code from 13.0.2000.0 to 13.0.3500.0

i am getting error when i try to create web service client in Spring STS

i am getting this error when try to create new web service client.
IWAB0503E Unable to update Java build path. Please check your system environment.
Some web searching uncovered that what this error really means is “The Web Services generation tool detected multiple versions of the javax.xml.soap plug-in installed. Resolve this error by removing the conflicting plug-in.”
Sure enough, when I checked in Eclipse there were two versions.
WebService
I encountered two speed bumps when testing this theory:
There’s no easy way to uninstall a plug-in within the Eclipse UI, so I had to resort to removing the directory from eclipse\plugins directly from Windows Explorer.
Which version should I remove? It took me two tries to figure out which version was causing the error. Turns out that newer is not always better…in this case 1.3 was at fault and 1.2 (javax.xml.soap_1.2.0.v200905122109) was the version to keep.
This is old but, in my case the details of the error were:
IWAB0503E Unable to update Java build path. Please check your system environment.
java.io.FileNotFoundException: /lib/saaj.jar
So \lib\saaj.jar was not found in folder
C:\sts-4.8.0\sts-4.8.0.RELEASE\plugins\javax.xml.soap_1.3.0.v201105210645\
I created the folder lib and copied saaj.jar in it from another STS instance that I had and then it worked.

I searched in net and understood that registry settings for VB are modified to VB5.I didnt understand that. please tell me how to resolve the error.
Its very URGENT

It might be possible, that something has corrupted your registry.
Try re-installing Visual Basic 6.0 including the latest Service Packs and then re-register all your additional COM components.

Runtime Exception: "CoCreateInstanceEx: The specified service does not exist as an installed service."

I just checked the latest source out of our repository after the installer (NSIS if it really matters) was created and a bug was discovered.
I started receiving the runtime exception CoCreateInstanceEx: The specified service does not exist as an installed service. on the following code:
Opc.IDiscovery discovery = new OpcCom.ServerEnumerator();
Opc.Server[] servers = discovery.GetAvailableServers(Opc.Specification.COM_DA_20);
Previous to creating the installer it seemed to work fine and this particular snippet of code hasn't been touched in weeks.
According to a quick search on the exception description, this probably has something to do with system drivers. But nothing has changed on the hardware (virtualized development system) and nothing has been installed since the check in where this code worked.
Any ideas on what caused this to break, and how do I fix this?
Hardware? This sounds like a COM DLL got unregistered - figure out what COM object is attempting to be instantiated and run regsvc32 on it.
